Mini-Circuits’ HFCW-422+ is a LTCC High Pass Filter with a passband from 4200 to 9000 MHz, supporting a vari- ety of applications. This model provides 1.2 dB typical passband insertion loss and provides a very good stopband rejection due to strategically constructed layout with minimal interaction between components. It provides a wide operating temperature range from -55 to +125°C. Housed in a tiny 0603 ceramic form factor with wrap-around ter- minations, the filter is ideal for dense PCB layouts and with minimal performance variation due to parasitics.
