Low-Cost Switched Filter Banks
Switched filter banks (SFBs) can have two to six channels and operate from 0.1 to 6.0 GHz in SMT or connectorized housings. Low insertion loss: 1:0 to 3.0 dB typ., return loss: 12 dB min., isolation: 22 to 60 dB, power supply: 5 VDC, switching speed 135 ns typ., prices as low as $250 for production quantities. This does not obsolete 3H robust mil SFBs that operate from 0.1 to 18.0 GHz, including high power options.

Passive MMIC Surface-Mount Bandpass Filter
The MFBP-00086CSP3 passive MMIC surface mount bandpass filter is an ideal solution for small form factor, high rejection filtering. The MFBP-00086CSP3 features a 12.7 to 17.9 GHz 1 dBc passband and 1.9 dB center frequency insertion loss. Passive GaAs MMIC technology allows production of smaller filter constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances allow for less unit-to-unit variation than traditional filter technologies. The MFBP-00086CSP3 is available in our 3.5 × 3.5 mm CSP3 chip scale package.
