Switched Filter Banks with Configurable Frequency Bands

API Technologies’ standard switched filter banks (310-020050-XXX series) offer customer-defined passband frequencies from 20 MHz to 7500 MHz with 2-7 channels. API’s switched filter banks have high isolation/rejection ( > 60 dB typical) and operate from a single +5.0V supply. Laser sealing and environmental ESS for high reliability applications as well as RoHS-compliant versions are available.

Features
  • Passband frequency 20 – 7500 MHz
  • Low insertion loss of < 5.0 dB
  • Fast switching speed of < 200 nanosecond as typical
  • High rejection > 60 dB typical
  • Small form factor

Filtered GPS Low Noise Amplifiers

API’s pre-filtered GPS LNA modules are designed to amplify GPS signals while protecting the front end of the GPS receiver by filtering out interferers from an increasingly crowded EM spectrum. The module leverages core competencies in low-loss filter, amplifier and mechanical design that results in a module that maximizes out of band rejection while minimizing system noise figure and maintaining a small size. The pre-filtered GPS LNA is offered in a wide range of performance options including GPS band configuration, gain level, supply voltage, multiple outputs and input and output connectors.

Features
  • Low Noise Figure
  • Wide Input Voltage Range
  • Tested to many MIL-STD-810 & MIL-STD-461 Requirements
  • Small Lightweight Hermetic Package

Custom Switched Filter Banks

API Technologies' Switched Filter Bank designs draw on an expertise in both microwave filters and control components. By combining filter and switch design capabilities, API can provide integrated switched filter assemblies that not only reduce the overall mechanical footprint, but also offer improved electrical performance. This enhanced performance is achieved by having the ability to align the filters to the switches, thus eliminating any mismatches.

Features
  • Improved VSWR
  • Less passband variation
  • Lower insertion loss
  • Reduced component count
