These are mixed by two double balanced mixers with the output signal generated by a first local oscillator providing the modulated signal. The modulated signal is then filtered by an IF filter. This filtered signal together with a signal generated by a second local oscillator is converted by a balanced mixer to produce the QPSK signal. The QPSK signal is amplified by a gain controlled amplifier to a level suitable for transmission. The gain of the controlled amplifier is bus controlled and this amplifier can be disabled when not transmitting to provide signal attenuation. The amplified signal is applied to an on-chip amplifier having two balanced outputs (open collector) linked to two chip resistors (values 150 ), and 9 V. The balanced outputs are designed to drive a 2 : 1 transformer (Siemens V944) with a 75 load giving an output level of 55 dBmV. The output frequency range of the transmitter is 5 to 40 MHz. The frequency of the first local oscillator operates at twice the frequency (i.e. 280 MHz) fixed by a Phase-Locked Loop (PLL) implemented in the circuit.

The VCO of both first and second local oscillators requires an external LC tank circuit with two varicap diodes. The data to the PLL is loaded in bursts framed by the signal EN. Programming rising clock edges and their appropriate data bits are ignored until EN goes active (LOW). The internal latches are updated with the latest programming data when EN returns inactive (HIGH). The last 14 bits are stored in the programming register. No check is made on the number of clock pulses received during the time programming is enabled. A wrong active clock edge will be generated causing a shift of data bits, if EN goes HIGH while CLK is still LOW. At power up, EN should be HIGH. The lock detector output LOCK is HIGH when both PLLs are in lock. The main divider ratio and the reference divider ratios are provided via the serial bus. A control register controls the Digital-to-Analog Converter (DAC), the output amplifier and the charge pump currents (Tables 1, 2 and 3).

OUTLINE VERSION SOT287-1 REFERENCES IEC JEDEC EIAJ EUROPEAN PROJECTION ISSUE DATE 95-01-25 97-05-22 1999 Dec 14 21 Philips Semiconductors Product specification QPSK transmitter SOLDERING Introduction to soldering surface mount packages This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 230 C. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: TDA8050 * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. 1999 Dec 14 22 Philips Semiconductors Product specification QPSK transmitter Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE WAVE BGA, SQFP PLCC(3), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes not suitable suitable(2) recommended(3)(4) recommended(5) suitable not not suitable suitable suitable suitable suitable HLQFP, HSQFP, HSOP, HTSSOP, SMS not TDA8050 REFLOW(1) 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale. This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later.
