ALM-1812-BLKG

ALM-1812 GPS Filter-LNA-Filter Front-End Module Data Sheet Description Features Avago Technologies’ ALM-1812 is a GPS front-end module that combines a high-gain low-noise amplifier (LNA) with GPS FBAR filters. 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/PCS-Band frequencies.          The low noise figure and high gain, coupled with low current consumption make it suitable for use in critical lowpower GPS applications or during low-battery situations.

Demoboard and application schematic diagram Notes 1. The module is fully matched at the input and output RF pins. The RFin pin is directly connected to a shunt inductor that is grounded. The RF output filter blocks DC. Best noise performance is obtained using high-Q wirewound inductors. This circuit demonstrates that low noise figures are obtainable with standard 0402 chip inductors. 2. C2 and L2 form a matching network that affects the frequency response and linearity of the LNA, these can be tuned to optimize gain and return loss. 3. L1 and R1 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 Vsd lines respectively. These components are not required in actual operation. 4. 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. 4 10 20 5 0 0 -40 -5 PCS band > 85 dBc -10 -60 -15 -80 -120 0 0.4 0.8 1.2 1.6 2 2.4 2.8 3.2 3.6 Freq (GHz) 4 5 0 0 -10 -15 -25 -30 -120 0.4 0.8 1.2 1.6 2 2.4 2.8 3.2 3.6 Freq (GHz) Figure 4a.
