RFMW Ltd. announces design and sales support for a front-end module (FEM) designed for GPS and GLONASS applications. TST’s TN0081A contains a high performance pre-SAW filter, low noise amplifier (LNA) and post-SAW filter providing 18.5 dB of in-band gain and very high out-of-band rejection of unwanted signals.

Relative to the center frequency of 1575 MHz, rejection is 85 dBc from 704 to 915 MHz and 75 dBc from 1710 to 1980 MHz. Noise figure is only 1.6 dB typical for 1575 MHz applications and 1.7 dB typical for 1597 to 1606 MHz applications.

The TN0081A draws only 3.3 mA from a 1.8 to 2.8 V supply and is offered in a very small 2.5 x 2.5 mm package requiring only two external components.
