Description
The SKY74073 SPRTM module combines all of the circuitry
required to design a dual-band EGSM900 and DCS1800 radio into
the world's smallest single package module. This small package
is approximately one-third the size of alternative radio solutions
and uses Skyworks low cost, multi-layer laminate substrate
technology. The SKY74073 can save handset designers
significant space and design-cycle time while providing a
roadmap for future multi-band and 3G applications.
The SPR module contains Skyworks certified Full Type Approval
(FTA), single-chip BiCMOS direct conversion transceiver
technology. Direct conversion architecture eliminates costly
Intermediate Frequency (IF) conversion steps while reducing the
number of components required to support multi-band GSM/GPRS
handsets. Agile channel switching enables support of GPRS multi-
slot operations. Translation loop architecture is used in the
transmit path. Transmit loop filters and all supporting circuitry are
also integrated in the SPR module. Impedance-matching for the
50
antenna port, I/O bias control circuitry, and DC blocking
circuitry are integrated into the module.
Two separate Heterojunction Bipolar Transistor (HBT) Power
Amplifier (PA) blocks are fabricated on a single Gallium Arsenide
(GaAs) die to provide maximum performance with the smallest
possible footprint. Optimized for lithium ion battery operation,
both PA blocks share common power supply pins. A custom
CMOS integrated circuit provides the internal interface to the PA.
The CMOS PA controller die also provides the antenna switch
decoding functionality. Transmit low pass circuitry designed to
filter out signal harmonics, a diplexer, and two receive Surface
Acoustic Wave (SAW) filters are also integrated in the radio
module.
The front-end radio circuitry uses two of Skyworks high
performance, low current consumption Pseudomorphic High
Electron Mobility Transistor
(
PHEMT), Single Pole Double Throw
(SPDT) GaAs switches. The switches typically draw less than
10
A of current during operation and are designed for low
insertion loss and high linearity performance.
Electrostatic Discharge (ESD) protection circuitry is integrated into
the SPR module and ensures the module's ruggedness under
extreme conditions.
