| We describe for the first time, a miniature GPS front-end module that achieves state-of-the-art gain and filtering in a single package. The module combines a E-mode pHEMT LNA MMIC with FBAR filter chip in a molded chip-on-board plastic package. At 2.7V supply voltage and 6mA current consumption, overall gain achieved is 19dB with 0.9dB noise figure. Filter rejection is better than 80dBc in the 827MHz and 72dBc in the 1.9GHz cellular frequency bands. The module is immune to signals up to -5.5dBm at the above frequencies, more than adequate to prevent gain compression in a S-GPS environment. The complete chip is housed in a 2-layer BTNX green material PC board and occupies an area of (3.3 x 2.1)mm. | | |
