Working Principle

The DEA165363BT-2124A3 is a typical interdigitated capacitor filter and can work in the range of 3.7 to 11GHz. This type of filter is composed of interdigitated capacitors, which are formed by interleaving the plates of two capacitors and form a three-dimensional structure. These filters have a wideband with good stopband performance. The device uses mechanical connection and wafer level packaging, and is also RoHS-compliant.

The filter has an input impedance of 50Ω± 1.5Ω and its frequency response can be adjusted by altering the width and the pitch of the capacitive plates. The input and output ports can either be balanced or single-ended.

The DEA165363BT-2124A3 is a low-power device with a power dissipation of 4dBm at 11GHz, and has excellent insertion loss and return loss performance. It features a VSWR of 1.4:1 at 7GHz and a VSWR
