Description
The design of the SKY77910-11 Transmit / Receive Front End Module
(FEM) offers a complete transmit VCO-to-Antenna and Antenna-to-
receive SAW filter solution for advanced cellular handsets comprising
quad-band GSM, and linear 2.5G operation. Developed in a very low
profile (0.8 mm) and compact form factor, the FEM supports Class 12
General Packet Radio Service (GPRS), EDGE multi-slot operation, and
TD-SCDMA and TDD LTE linear transmission. Eight transmit / receive
(TRx) ports and an integrated directional coupler enables broadband
3G/4G RF switch-through.
The module consists of a CMOS Power Amplifier (PA) Controller, a low
band (LB) PA block supporting GSM850/900 bands, a high band (HB) PA
block supporting DCS1800/PCS1900, TD-SCDMA bands 34/39, and
TDD LTE band 39, input and output ports internally matched to 50 ohm
impedance loads, Tx harmonic filtering, RF switching, and a directional
coupler at the antenna output. The custom low-current PA controller
includes the Mobile Industry Processor Interface (MIPI) and decoder
circuitry to control the RF switch.
Internal matching of all RF ports to a 50 ohm load reduces the number
of external components on the phone board. The Heterojunction Bipolar
Transistor (HBT) PA blocks, fabricated in GaAs, share common power
supply pads to distribute current. Extremely low leakage current of the
SKY77910-11 maximizes handset standby time. The PA outputs and the
eight TRx pads connect to the antenna pad through a high-linearity,
low-loss switch. The TRx ports feature a 0 volts DC offset level that
eliminates external blocking capacitors. An integrated directional
coupler precludes any external coupler requirement. The GaAs die, the
switch die, the CMOS controller, and the passive components mount
onto a multi-layer laminate substrate and the entire assembly is
encapsulated with plastic overmold. MIPI controls the RF signal flows
including mode control and selection of LB or HB PA or TRx port.
In GMSK modes, the PA controller provides envelope amplitude control
as a function of VRAMP and reduces sensitivity to input drive,
temperature, power supply, and process variations. Skyworks’ Finger-
Based Integrated Power Amplifier Control (FB-iPAQ) minimizes output
power variation into mismatch. Proper timing of MIPI commands and
VRAMP input ensures high isolation between the antenna and Tx-VCO
while the VCO is being tuned prior to the transmit burst.
In EDGE and TD-SCDMA / TDD LTE linear modes, VRAMP voltage and
MIPI-based bias settings optimize PA linearity and efficiency.
