RF3158 GSM/EDGE PowerStar 6x6mm Power Amplifier Module

Ideally suited for 3V quad-band GSM/GPRS and EDGE handset applications, the compact RF3158 is fully integrated and requires no external routing or external components. Designers will benefit from a simplified layout and reduced board space, while also seeing the benefits of integrated power control and automatic VBATT tracking technology...

Details

The RF3158 is a high-power, dual-mode PowerStar® power amplifier (PA) with integrated power control contained in a small 6x6mm square footprint. Manufactured on an advanced GaAs HBT process technology, this PA solution is designed to operate both in a saturated mode for GMSK signaling and in a linear mode for 8PSK modulation.

Featuring input and output terminals that are internally matched to 50 ohms, the RF3158 is designed to be the final amplification stage in a dual-mode GSM/EDGE mobile transmit lineup operating in the 824 MHz to 915 MHz (low) and 1710 MHz to 1910 MHz (high) bands. The module solution is applicable to EDGE systems requiring a linear PA such as those using direct I&Q modulation or those using small signal polar modulator techniques. A single input pin allows for analog power control in GPRS mode and two digital steps when in 8PSK mode.
