ALM-1412
GPS LNA-Filter Front-End Module
Data Sheet
Description
Features
Avago Technologies’ ALM-1412 is an LNA module, with
integrated filter, designed for GPS band applications at
1.575GHz. 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’ leadingedge FBAR filter for exceptional rejection at Cell/PCSBand frequencies.

The demoboard of Figure 6 is Rogers® RO4350 with typical Dk=3.48 (@10GHz).
L3 and the module’s internal input pre-match form the input matching network. The RFin pin, pin 1, is directly connected to a shunt inductor
that is grounded. The RF output filter blocks DC.
This circuit demonstrates that very low noise figure is obtainable with standard 0402 chip inductors instead of high-Q wirewound inductors.
C2 and L2 form a matching network at the output of the LNA stage, which can be tuned to optimize gain and return loss. For example, higher
gain can be obtained by increasing the value of C2 but at the expense of stability. Changing the value of L2 can improve the PCS rejection,
but impacts output return loss.
L1 is a choke which isolates the demoboard from external disturbances during measurement. It is not needed in actual application. Likewise,
C1 and C3 mitigate the effect of external noise pickup on the Vdd and SD lines respectively. These components are not required in actual
operation.
R1 is a stability-enhancing resistor.
C9 is a DC-blocking capacitor. It is also not required in actual operation.
Bias control is achieved by either varying the SD voltage (Vsd) with/without R2, or fixing the SD voltage to Vdd and adjusting R2 for the desired
current. Typical value for R2 is 10k Ohms for 8 mA total current at Vdd = 2.85 V and Vsd = +2.60 V. For applications where it is more appropriate
to have SD (Vsd) connected to Vdd, a 12 k Ohms resistor value for R2 is suggested (where Vdd = 2.85 V).
For low-voltage operation such as Vdd = 1.5 V or 1.0 V, R2 may be omitted and SD (Vsd) connected directly to Vdd.
The grounding regime for the ALM-1412 is critical to achieving the PCS- and Cell-Band Rejections shown in Figure 9. Please refer to the PCB
Land Patterns section of this document for the exact locations of the grounding vias.

Notes:
• The exceptional noise figure performance of the ALM-1412 is due to its highly optimized design. In this regard, the Fmin of the ALM-1412
shown above is locked down by the internal input pre-match. This allows the use of relatively inexpensive chip inductors for external
matching.
• The NF performance of the ALM-1412 is also very resilient to operating conditions. For example, at Idd = 4.5 mA, the degradation in NF is only
0.1 dB, and not more than 0.15 dB degradation over temperature.
