CX77304-15
PA Module for Dual-band GSM850 PCS1900 / GPRS Applications
The CX77304-15 Power Amplifier Module(PAM) is designed in a compact form factor
for dual-band cellular handsets comprising GSM850 and PCS1900 operation. It also
supports Class 10 General Packet Radio Service (GPRS) multislot operation.
The module consists of separate Heterojunction Bipolar Transistor (HBT) PA blocks
for the GSM850 and PCS1900 bands, interface circuitry, and RF input and output
ports internally matched for 50
impedance to reduce the number of external
components. The PA blocks are fabricated on a single Gallium Arsenide (GaAs) die
and share common power supply pins for current distribution.
Extremely low
leakage current (2
A, typical) of the dual PA module maximizes handset standby
time.
The CX77304-15 also contains band-select switching circuitry to select GSM
(logic 0) and PCS (logic 1) as determined from the Band Select (BS) signal. In the
block diagram shown below, the BS pin selects the PA output (PCS OUT or
GSM OUT) while the Analog Power Control (APC) controls the level of output power.
A custom CMOS IC provides the internal interface circuitry including
a current
amplifier that minimizes the required power control current (IAPC) to 10
A,
typical. The GaAs die, the Silicon (Si) die, and passive components are mounted
on a multi-layer laminate substrate and the assembly encapsulated with plastic
overmold.
