ALM-3012
GNSS LNA-Filter Front-End Module
with optional Differential Outputs
Data Sheet
Description
Avago Technologies’ ALM-3012 is an ultra low-noise
GNSS (Global Navigation Satellite System) front-end
module that combines a low-noise amplifier (LNA) with
a GNSS FBAR post-LNA filter, supporting both GPS and
GLONASS operating in 1565 ~ 1606 MHz frequency range.
The module can be used both as a single-ended and
pre-matched differential outputs. The LNA uses Avago
Technologies’ 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 adjustment. The integrated filter utilizes an Avago
Technologies’ leading-edge FBAR filter for exceptional
rejection at Cellular, DCS, PCS and WLAN band frequen-
cies. Bypass functionality with an external RF switch is
possible with separate RF switching.
The ALM-3012 is usable down to 1.8 V operation. It
achieves low noise figures and high gain even at 1.8 V,
making it suitable for use in critical low power GNSS band
applications.
