Description

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 possible 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.
