A IF signal can be applied to this pin and up–converted to the desired RF frequency. 2. A resistor can be connected to ground, controlling the RF output power. 3. A resistor can be connected to VCC, disabling the entire mixer. The linear gain of the Mixer/Buf when used as a buffer is approximately –5.0 to –8.0 dB. Mixer/Buffer Outputs The mixer outputs (Mixer/Buf Out + and Mixer/Buf Out –) are balanced, open collector. A shunt resistor of 200 Ω minimum to VCC is recommended for stability. The outputs can be used as a single–ended driver or connected in a balanced–to–unbalanced configuration. If the single–ended driver configuration is used, the unused output must be tied directly to V CC . F o r t h e balanced–to–unbalanced configuration, an additional 3.0 to 6.0 dB of power gain can be achieved. Conjugate matching is easily accomplished to the desired load by the addition of a shunt and series element (see Table 2, S22 parameters). Low Power Amplifier (LPA) The LPA is internally biased at low supply current (approximately 2.0 mA emitter current) for optimal low power operation, yielding a 10 dBm 1.0 dB output power compression point. Input and output matching may be achieved at various frequencies using few external components (see Table 3 S–parameters). Typical power gain is 16 dB with the input/output conjugately matched to the source/load impedance. A minimum 200 Ω shunt resistor from the output to VCC is recommended for stability.
