Device Overview
General Description
The MFBA-00004CH family of passive MMIC bandpass filter die are an ideal solution for small form factor, high rejection filtering. 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 MFBA-00004CH is available as a wire bondable chip. Low unit to unit variation allows for accurate simulations using the provided S2P file taken from measured production units.
Features
- Excellent Return Loss
- High Stop Band Suppression
- Wide Stop Band with Fast Roll-Off
