Description
SkyLiTE^™ is Skyworks’ newest family of LTE devices which consists of
highly integrated modules incorporating the amplification, switching,
WiFi filtering and coupler functions required to support all major
FDD/TDD bands. With the addition of external duplexers, this product
family provides OEMs with a scalable and reconfigurable front-end
system suitable for markets worldwide.
SKY77916-11 SkyLiTE^™ is a key building block for global or five-mode
front-end implementation. As a Transmit / Receive Front-End Module
(FEM), the SKY77916-11 SkyLiTE^™ supports 3G / 4G handsets and
operates efficiently in WCDMA, TD-SCDMA, and LTE modes. The
module is fully programmable through a Mobile Industry Processor
Interface (MIPI^®).
By design, this Tx-Rx Front End Module 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 compact form factor, it features a very low
profile of 0.8 mm (Max.). The SKY77916-11 supports Class 12 General
Packet Radio Service (GPRS) and EDGE multi-slot operation, and TD-
SCDMA and TDD LTE linear transmission. Fourteen 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 to support GSM850/900 bands and a high band (HB)
PA block to support DCS1800/PCS1900, TD-SCDMA bands 34/39, and
TDD LTE band 39. Also included are RF 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.
All RF ports are internally matched to 50 ohm impedance to minimize
external components on the phone board. The GaAs fabricated
Heterojunction Bipolar Transistor (HBT) PA blocks share common power
supply pads to distribute current. Extremely low leakage current of the
SKY77916-11 maximizes handset standby time. Fourteen TRx pads and
the PA outputs connect to the antenna 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 requirements.
The GaAs die and the switch die, the CMOS controller, and passive
components are mounted on a multi-layer laminate substrate with the
entire assembly encapsulated with plastic overmold.
