Description
SKY77590-51 is a transmit and receive Front End Module (FEM) designed in a very low profile
(0.9 mm) and compact form factor for quad-band cellular handsets comprising GSM850/900,
DCS1800, and PCS1900 operation and dual-band TD-SCDMA bands 34 and 39 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 and linear EDGE
operation. 3G switch-through support is provided by six dedicated high-linearity ports.
The module consists of a GSM850/900 PA and DCS1800/PCS1900/TD-SCDMA PA block,
impedance-matching circuitry for 50 input and output impedances, Tx harmonic filtering, a
high linearity/low insertion loss switch, and a CMOS Power Amplifier Control (PAC) block. A
custom silicon integrated circuit contains decoder circuitry to control the RF switch while
providing a low current, external control interface.
Fabricated in InGaP/GaAs, the Heterojunction Bipolar Transistor (HBT) PA blocks support the
GSM850/900 bands and DCS1800/PCS1900 bands and TD-SCDMA bands 34/39. Both PA
blocks share common power supply pads to distribute current. The output of the PA block and
the outputs to the six receive pads connect to the antenna pad through a high-linearity antenna
switch. The 3G and Rx ports feature a 0 volts DC offset level which eliminates the 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.
RF input and output ports of the SKY77590-51 are internally matched to a 50 load to reduce
the number of external components on the phone board. Extremely low leakage current of the
FEM maximizes handset standby time. Control of transmit and receive RF signal flows, and
band selection are performed by four external control pads (see Figure 1 on overleaf). Mode of
operation, Tx vs. Rx, and Band (GSM850, GSM900, DCS1800, PCS1900, and Bands 34/39) are
controlled with the four logic inputs: Mode, TxEN, BS1, and BS2. Proper timing of the TxEN
input and the VRAMP input ensures high isolation between the antenna and Tx-VCO while the
VCO is being tuned prior to the transmit burst.
The integrated power amplifier control (PAC) function provides envelope amplitude control
while reducing sensitivity to input drive, temperature, power supply, and process variation.
Output power variation into mismatch is minimized with Skyworks’ True Power control circuit.
