Description

Local signal input pin

VDD pin of local amplifier

GND pin

VDD pin of RF amplifier

GND pin

Antenna switch pin.

This pin is ANT1-Tx or ANT1-Rx by setting of VCTL1 and VCTL2.

Antenna switch pin.

This pin is ANT2-Tx or ANT2-Rx by setting of VCTL1 and VCTL2.

Antenna switch control 1 pin

Tx pin. Signal is input to antenna switch during ANT-Tx.

Power amplifier output pin

Connection pin of external capacitor (for noise elimination)

Gate voltage adjustment pin of power amplifier (first stage, middle stage,

rear-end FET)

Signal input pin to power amplifier

GND pin

VDD1 pin of power amplifier (first stage FET)

VDD2 pin of power amplifier (middle stage FET)

VDD3 pin of power amplifier (rear-end FET)

GND pin

Rx pin. ANT input signal is output to this pin during ANT1-Rx or ANT2-Rx.

Antenna switch control 2 pin

RF signal input pin

External capacitor connection pin.

This pin is connected to LNA FET source. RF amplifier characteristic is

optimized during 1.9GHz by the capacitor of 13pF (Typ.).

GND pin

External capacitor connection pin.

IF amplifier distortion is improved by this capacitor.

IF output and IF AMP, MIX VDD
