Compact, Low-Profile Antenna Accepts GPS Signals

Antenna element, low-noise amplifier, and pre-select bandpass filter are all integrated into a compact module for receiving 1575.42-MHz GPS signals with a passband width of 9 MHz. Antenna gain is +5.0 dBi (typ.) with a 90° elevation angle; module power requirement is 5V and its current consumption is 15 mA with no signal; and the power gain of the GaAs FET LNA is 31 dB while the noise figure is a low, 0.9 dB (typ.).The TMM869 module comes packaged in a low-profile radome of
