SA910 Datasheet Variable Gain Rf Predriver Amplifier

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: INTEGRATED CIRCUITS SA910 Variable gain RF predriver amplifier Product specification 1997 Aug 12 Philips Semiconductors Philips Semiconductors Product specification Variable gain RF predriver amplifier.

General Description

The SA910 is a variable gain predriver amplifier designed for handheld analog cellular telephones.

When used with a UHF power transistor, it forms a cost-effective, low-profile, surface mount power amplifier solution (1.2W maximum PAE > 50%).

The SA910 integrates power detection and control circuitry that is stabilized over temperature and voltage.
