TW4037/TW4039 Low Gain GPS Antenna

The TW4037/TW4039 are very low power,

compact GNSS antennas covering the GPS L1,

frequency band. This antenna features an LNA

with constant performance from 2.7V to 5.5V

supply voltage, and includes protection against

close-proximity 700MHz LTE and L-band

transmitting antennas.

The TW4037/TW4039 provide a minimum

gain of 15dB and 12dB, respectively and

excellent noise figure. The TW4037/TW4039

patch has 40% wider bandwidth for better axial

ratio and has 15 KV ESD circuit protection. The

LNA has a +/- 10MHz bandwidth that covers

the full GPS L1 signal plus the SBAS (WAAS

/EGNOS/MSAS) frequency band (1572.5 to

1578 MHz).

The TW4039 variant provides a “Brick-Wall”

pre-filter to protect against saturation by high

level sub-harmonics and L-Band signals.

It is housed in a compact IP67 magnetic mount

enclosure.
