Dualband SiGe-Power Amplifier for GSM 900/1800/1900
Description
The TST0911 is a monolithic dualband power amplifier
IC. The device is manufactured using TEMIC
Semiconductors’ advanced Silicon-Germanium (SiGe)
process and has been designed for use in GSM-based
cellular phones.
The IC offers the functionality of two
amplifiers in one package and is suited for
GSM 900/1800/1900 (GSM/ DCS/ PCS) dual- or triple
mobile phones. With a single supply voltage operation of
3 V and a neglectable leakage current in power-down
mode, the TST0911 needs few external components.
Features
900-MHz amplifier and 1800/1900-MHz amplifier
for dual-/tripleband application
35 dBm output power @ 900 MHz
32 dBm output power @ 1800/ 1900 MHz
Power-added efficiency (PAE) 50%
