Description

Interface Schematic

RF high band output. Open collector output.

The output should be biased at VCC through an inductor that can be used

to form part of an output matching circuit.

In our proposed applications circuit some power is dissipated in R4 (180Ω)

which appears as a de-Qing resistor in parallel with the output inductor L3.

If R4 is eliminated and the RFOUT HB pin is re-matched to 50Ω it is possi-

ble to get approximately 3dB extra power out of the device in high band

mode.

Ground for RF output sections.

Ground for modulator, variable gain amplifier and substrate.
