| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MRFIC1813/D The MRFIC Line 1.9 GHz GaAs Upconverter Designed primarily for use in wireless Personal Communication Systems (PCS) applications such as Digital European Cordless Telephone (DECT), Japan's Personal Handy System (PHS) and the emerging North American systems. The MRFIC1813 is also applicable to 2.4 GHz ISM equipment. The device combines a balanced upmixer and a transmit exciter amplifier in a low-cost TSSOP-16 package. Minimal off-chip matching is required while allowing for maximum flexibility and efficiency. The mixer is optimized for low-side injection and provides more than 12 dB of conversion gain with over 0 dBm output at 1 dB gain compression. Image filtering is implemented off-chip to allow maximum flexibility. A CMOS compatible ENABLE pin allows standby operation where the current drain is less than 250 mA. Together with other devices from the MRFIC180X or the MRFIC240X series, this GaAs IC family offers the complete transmit and receive functions, less LO and filters, needed for a typical 1.8 GHz cordless telephone or 2.4 GHz ISM band equipment. * Usable Frequency Range = 1.7 to 2.5 GHz * 15 dB Typ IF to RF Conversion Gain * 3 dBm Power Output Typ, 0 dBm Minimum at 1 dB Gain Compression * Simple Off-chip Matching for Maximum Flexibility * Low Power Consumption = 75 mW (Typ) * Single Bias Supply = 2.7 to 4.5 Volts * Low LO Power Requirement = - 5 dBm (Typ) * Low Cost Surface Mount Plastic Package * Order MRFIC1813R2 for Tape and Reel.

Table 1. Port Impedances versus Frequency (VD1, VD2, VD3, TX EN = 3 Vdc) APPLICATIONS INFORMATION DESIGN CONSIDERATIONS The MRFIC1813 combines a single-balanced MESFET mixer with an exciter amplifier. It is usable for transmit frequencies from 1.7 to 2.5 GHz and IF frequencies from 70 to 350 MHz. The design is optimized for low-side local oscillator injection in hetrodyne transmit applications. Minimal off-chip matching is required while allowing for flexibility and performance optimization. An active balun is employed at the IF port which gives good balance down to at least 70 MHz. A passive splitter is used at the LO input to complete the single-balanced configuration. CIRCUIT CONSIDERATIONS Figure 1 shows the application circuit used to gather the data presented in the characterization curves. As shown in Table 1, the IF port impedance is very high. Three hundred ohms was chosen for R1 to shunt the IF port as a compromise of gain and bandwidth. A 50 resistor can be used and L1 and C5 eliminated to provide a broadband match. The EVALUATION BOARDS Evaluation boards are available for RF Monolithic Integrated Circuits by adding a "TF" to the device type. For a complete list of currently available boards and one in development for newly introduced products, please contact your local Motorola Distributor or Sales Office. conversion gain is reduced to about 8 dB. Microstrip inductors T1 and T2 combine with inductance internal to the device to form RF chokes. Some tuning of the RF output can be achieved with T1. As with all RF devices, circuit layout is important. Controlled impedance lines should be used for all RF and IF interconnects. As shown in Figure 1, power supply by-passing should be used to avoid device instability. Ground vias should be included near all ground connections indicated in the schematic. Off-chip components should be mounted as close to the IC leads as possible. MRFIC1813 6 MOTOROLA RF DEVICE DATA PACKAGE DIMENSIONS A -PK NOTES: 1.
