Data Sheet
Description
Features
Very Low Noise Figure: 1.26 dB typ.
Exceptional Cell/DCS/PCS/WLAN-Band rejection
Advanced GaAs E-pHEMT & FBAR Technology
Low external component count.
CMOS compatible shutdown pin (SD)
ESD: > 3kV at RFin pin
Avago Technologies’ ALM-2712 is an ultra low-noise GPS
front-end module that combines a low-noise amplifier
(LNA) with GPS FBAR filters. The LNA uses Avago Tech-
nologies’ proprietary GaAs Enhancement-mode pHEMT
process to achieve high gain with very low noise figure
and high linearity. Noise figure distribution is very tightly
controlled. A CMOS-compatible shutdown pin is included
either for turning the LNA on/off, or for current adjust-
ment. The integrated filter utilizes an Avago Technologies’
Adjustable bias current via single external resistor/
voltage
leading-edge FBAR filter for exceptional rejection at Useable down to 1.8V supply voltage

Cellular, DCS, PCS and WLAN band frequencies. Bypass
functionality with an external RF switch is possible with
separate RF switching.
Small package dimension: 3.0(L)x2.5(W)x1(H) mm
Meets MSL3, Lead-free and halogen free
Specifications (Typical performance @ 25°C)
At 1.575GHz, Vdd = 2.7V, Idd = 7.5mA
Gain = 14.2 dB
The low noise figure and high gain, coupled with low cur-
rent consumption make it suitable for use in critical low-
power GPS applications or during low-battery situations.

Notes:
The ALM-2712 can be operated with supply voltage (Vdd) from 1.5V to 2.85V. Vsd can operate from 1V to Vdd.
The module is fully matched at the input and output RF pins. The RFinput pin is connected directly to a shunt inductor to ground. As such a DC
blocking capacitor is required if DC voltages are present. The RFoutput pin is already DC-blocked by the internal filter inside the module.
Best noise performance is obtained using high-Q wirewound inductors. This circuit demonstrates that low noise figures are obtainable with
standard 0402 chip inductors.
C1 and C2 are bypass capacitors for RF and low frequency stability and linearity .
L1 and R1 isolates the demoboard from external disturbances during measurement. It is not needed in actual application. Likewise, C3 mitigate the
effect of external noise pickup on the Vsd line. This component are not required in actual operation. Minimal component operation is as shown in
the schematic on page 1.
Bias control is achieved by either varying the Vsd voltage with/ without R2, or fixing the Vsd voltage to Vdd and adjusting R2 for the desired current.

Notes:
The exceptional noise figure performance of the ALM-2712 is due to its highly optimized design. In this regard, the Fmin of the ALM-2712 shown
above is locked down by the internal input pre-match. This allows the use of relatively inexpensive chip inductors for external matching.
