SA910 - Variable gain RF predriver amplifier
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 circuitr
