In the AMPS mode the TQ5132 switches the IF output to the

AMPS pin and turns on the RF amplifier but at lower current

than CDMA mode. Thus the system draws much less current

in AMPS mode.

In the High Gain modes, a cascode amplifier is switched in

before the mixer. Control for this function is made via a DC

signal on the RF input pin 1. The IF amplifier gain can be

stepped as well via a control line at pin 6.

The CDMA Mid Gain Mode provides an intermediate gain step.

The mixer has the RF amplifier turned off and the IF stage at

minimum gain.

In the low gain modes, the RF amplifier is disabled and the input

signal is routed directly to the mixer.
