Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. Each absolute maximum rating listed is an individual parameter. Basing and driving the amplifier with all absolute maximum ratings listed simultaneously may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times.

Gerber files available upon request. Incorrect soldering of the device paddle to grounding pad may lead to parasitic oscillations, reduced performance and increased device temperature rise. Uniform coverage over the entire bottom ground paddle must be maintained to avoid these conditions.

E DATA SHEET * SKY65111-348LF Application Circuit Notes Ground, (Pins 1, 3, 8, 14). Attach all ground pins to the RF ground plane with the largest diameter and lowest inductance via that the layout will allow. Multiple small vias are also acceptable and will work well under the device if solder migration is an issue. It is extremely important that the device paddle be sufficiently grounded for both thermal and stability reasons. Please refer to the enclosed Package Footprint. RF input (Pin 2). A lumped element matching structure for good in-band return loss has been realized on the RF input, Pin 2. This structure is comprised of a DC blocking capacitor (C1), low pass LC filter (L1, C1) and at the device input, a series capacitor (C25). This combination of devices will yield a return loss better than 11 dB over the entire 800-1100 MHz band of interest. The placement of C1 is not critical; it can be moved as close to L1, C2 and C25 as desired. C25 should be placed as close to the device pin as possible to replicate performance as measured on the applications board. VCC1 (Pin 4). VCC1 is the collector bias for the first amplifier stage in the SKY65111. Multiple bypass capacitors, C3-C5, C17 and a series inductor, L2, have been utilized to ensure stability both in and out of the useable bandwidth of the device. The length of transmission line between L2 and Pin 4 is not critical; L2 can be placed as close to the pin as possible if desired. However, placement of L2 farther away from Pin 4 than shown on the Applications Circuit is not recommended. C3 should also be placed in the approximate location shown on the Applications Circuit, but placement is not critical. VAPC1 (Pin 5). VAPC1 is the bias control voltage input for amplifier stages 1 and 2. Nominal operating range is between 2.6 VDC and 2.8 VDC, with 3 VDC producing the minimum attenuation point. VAPC1 may also be set to 0 VDC, to force stages 1 and 2 into standby mode. VAPC2 (Pin 6). VAPC2 is the bias control voltage for amplifier stage 3. Nominal operating range is between 2.6 VDC and 2.8 VDC, with 3 VDC producing the minimum attenuation point. A 100 pF capacitor (C19) may be used for bypassing at high frequencies. The value of this capacitor may also be made large, greater than 1000 pF, if longer response time is acceptable. VAPC2 may also be set to 0 VDC, to place amplifier stage 3 into standby status. VREF (Pin 7). VREF is the bias reference voltage for amplifier stages 2 and 3. VREF should be operated over the same voltage range as VCC, with a nominal voltage of 3.5 VDC. Bypassing of VREF is accomplished with C22 and C23 which should be placed as close to the device pin as possible. RFOUT, VCC3 (Pins 9-12). RFOUT and VCC3 are the biasing input of the stage 3 collectors. Bias is applied to the RF output through a length of transmission line that is approximately 827 mils (21 mm) long. Capacitors C11-C14 provide proper RF bypassing and should be placed as shown in the Applications Circuit. Output matching for optimal power gain is accomplished with capacitors C15 and C16. Spacing between these capacitors with respect to the RF output and each other is critical and is shown on the Component Placement Diagram. Special care must be taken when placing these devices; their locations should not deviate significantly from the locations as shown. If these capacitors are not located properly, large decreases in output power and efficiency will occur. Pin 13. Pin 13 has no connection and should be left open circuit. VCC2 (Pins 15-16). VCC2 is the collector bias input for the second amplifier stage in the SKY65111. Multiple bypass capacitors, C8-C10 have been utilized to ensure stability both in and out of the useable bandwidth of the device. Capacitor C7 is not populated with the normal tuning configuration described above. NOTE: In most applications VAPC1 and VAPC2 pins are directly tied together and biased from the same control voltage. VAPC1 and VAPC2 may also be split if independent control is desired.

With the RF off, apply 2.7 VDC to VAPC1, 2 control pins. Verify the ICQ current is approximately 250 mA, labeled 3. Step 4. Apply RF signal data -30 dBm level and observe that the output level is approximately 10 dBm or the gain of the device is approximately 40 dB. 1 GND 2 NOTE: It is important that the VCC1, VCC2, VCC3, and VREF voltage source be adjusted such that 3.5 V is measured at the board. The high collector currents will drop the collector voltage significantly if long leads are used. Adjust the bias voltage to compensate.
