SAW filters are made for GPS receivers

Temex has a new RF SAW filter for GPS receivers ideally suited to marine navigation, automotive, and recreational applications.

Temex has a new RF SAW filter for GPS receivers ideally suited to marine navigation, automotive, and recreational applications.

One of the most critical and essential elements of GPS receiver design is filtering at the RF stage.

RF filters must be capable of combining a low insertion loss and high rejection.

Designed for standard GPS applications, TMX W007 offers the best insertion loss/rejection tradeoffs of the market, and a miniature surface-mount device (SMD) packaging to meet the needs of small-form-factor GPS receivers.

TMX W007 has an absolute attenuation of 40dB minimum at 1710MHz.

The filter centre frequency is 1575.42MHz with a bandwidth of 2.4MHz over a temperature range of -40 to +85C.

TMX W007 is available in a lead-free SMD 2.5 x 2 x 0.9mm package.

At about half the size, Temex also offers the TMX W314, which has an absolute attenuation of 35dB minimum at 1710MHz.

The TMX 314 has a bandwidth of 2.4MHz over a temperature range of -40 to +85C and is available in a ceramic SMD 2 x 1.6 x.8mm package.

Both filters are RoHS compliant and available in a fully lead-free version.

Custom designed GPS SAW filters are also available on request.
