Mini-Circuits’ Model HPCJ-03-422+ is an LTCC 3 dB, 90° hybrid splitter/combiner operating from 3200 to 4200 MHz and supporting a variety of applications.  This model provides 0.14 dB typical average insertion loss above 3 dB, 26 dB typical isolation and handles up to 50W RF input power when used as a splitter. Featuring optimized phase and amplitude unbalance, this quadrature hybrid enables operation over a wide temperature range of -55 to +125 °C. Housed in a small 0.2” x 0.125” x 0.079” form factor, the unit is ideal for dense PCB layouts and exhibits minimal performance variation due to parasitics.
