DATA SHEET CX77304-16 PA Module for Tri-Band EGSM DCS PCS / GPRS Applications • Tri-band cellular handsets encompassing - Class 4 EGSM900 - Class 1 DCS1800 - PCS1900, and - Up to Class 10 GPRS multislot operation Description The CX77304-16 Power Amplifier Module (PAM) is designed in a compact form factor for tri-band cellular handsets comprising EGSM900, DCS1800, and PCS1900 operation. It also supports Class 10 General Packet Radio Service (GPRS) multislot operation. The PAM consists of separate Heterojunction Bipolar Transistor (HBT) PA blocks for EGSM900 and DCS1800/PCS1900 PA bands, interface circuitry, and RF input and output ports internally matched to 50 W to reduce the number of external components. The PA blocks are fabricated on a single Gallium Arsenide (GaAs) die.
