GNSS SAW filters in the TA Series cover GPS-only and multi-constellation combinations including GLONASS, GALILEO, BEIDOU and COMPASS. The range is offered across several footprint options, starting from 1.1 × 0.9 mm and extending to 3.8 × 3.8 mm, supporting dense RF layouts. Defined bandwidth options include narrowband 2 MHz parts for GPS band filtering as well as wider-band parts around 34–57 MHz for multi-constellation reception. Insertion loss values span from 0.8 dB up to 3.5 dB depending on the selected part and band plan. Several part numbers are marked as AEC-Q200, supporting designs where automotive-grade qualification is required. The selection also includes specific variants for additional GNSS-related bands such as L2 and L5/E5 and a dedicated BEIDOU option.

FAQs
for TA Series GNSS SAW Filters Surface Acoustic Wave Filters
GNSS SAW filters are used to improve selectivity in GNSS receiver front ends by filtering the desired satellite band while reducing out-of-band interference. TA Series GNSS SAW filters provide defined centre frequency, insertion loss and bandwidth parameters to support predictable RF filtering behaviour.
The GNSS SAW filters list includes GPS-only parts as well as multi-constellation options labelled for combinations such as GPS + GLONASS and GPS + GLONASS + GALILEO + BEIDOU. A COMPASS-labelled variant is also included within the GNSS SAW filters range.
Several TA Series GNSS SAW filters are marked as AEC-Q200, indicating availability of parts intended for automotive-grade qualification requirements. Selecting an AEC-Q200 GNSS SAW filter is typically aligned with designs where qualification marking is needed at component level.
Centre frequency and bandwidth selection should match the targeted GNSS band plan and whether reception is narrowband GPS band filtering or wider multi-constellation coverage. The TA Series GNSS SAW filters include narrow 2 MHz GPS-band options and wider bandwidth options around 34–57 MHz for broader reception.
The GNSS SAW filters are listed in multiple footprints, starting at 1.1 × 0.9 mm and extending to larger packages such as 3.8 × 3.8 mm. Package choice is typically driven by layout density, routing constraints and the required part number option.
Dedicated variants are listed for GPS + GLONASS L2 and for GPS L5 + GLONASS E5 within the GNSS SAW filters table. These options support designs where filtering is required beyond the main GNSS L1-related band coverage.
Insertion loss values in the GNSS SAW filters range span from 0.8 dB to 3.5 dB depending on the selected part number and target band. Selecting a TA Series GNSS SAW filter involves balancing insertion loss against bandwidth and footprint requirements.
The TA Series GNSS SAW filters include compact footprints down to 1.1 × 0.9 mm and several 1.4 × 1.1 mm options, supporting high-density integration. A car-antenna-labelled option is also listed within the GNSS SAW filters selection, which may align with antenna-associated GNSS designs.
