Description
SKY77573-31 is
a transmit and receive Front End Module (FEM) designed in a very low profile
(0.9 mm), compact form factor for quad-band cellular handsets comprising GSM850/900,
DCS1800, and PCS1900 operation—a complete transmit VCO-to-Antenna and Antenna-to-
receive SAW filter solution. The FEM also supports Class 12 General Packet Radio Service
(GPRS) multi-slot operation, EDGE Linear Modulation, and TD-WCDMA (Bands 39/34). WCDMA
switch-through support is provided by four dedicated high-linearity ports.
The module consists of a GSM850/900 PA and DCS1800/PCS1900 PA block, impedance-
matching circuitry for 50
input and output impedances, Tx harmonic filtering, high linearity-
low insertion loss switches, and a Multi-Function power amplifier Control (MFC) block.The
internal MFC function and interface circuitry is provided by a BiCMOS IC.
.
Fabricated in InGaP/GaAs, the Heterojunction Bipolar Transistor (HBT) PA blocks support the
GSM850/900 bands and DCS1800/PCS1900 bands. Both PA blocks share common power
supply
pads to distribute current. The output of the PA block and the outputs to the eight
receive pads connect to the antenna pad through a highly linear antenna switch. The WCDMA
and Rx ports feature a near 0 volts DC offset level, which eliminates any need for external
blocking capacitors. The InGaP/GaAs die, switch die,
Silicon
(Si) controller die, and passive
components are mounted on a multi-layer laminate substrate and the entire assembly is
encapsulated with plastic overmold.
The SKY77573-31
RF I/O ports are internally matched to a 50
load to reduce the number of
external components for a quad-band design. Extremely low leakage current of the FEM
maximizes handset standby time. Band selection and control of transmit and receive RF signal
flows are performed via six external control pads (see Figure 1). Mode of operation, Tx, Rx,
Band (GSM850, GSM900, DCS, PCS, and UMTS) are
controlled
through the 7 logic inputs
LB_EN, HB_EN, MODE0, MODE1, SW0, SW1, and SPDT.
