The typical insertion loss (above the 6 dB power split) is 1.1 dB from 18 to 40 GHz and 1.6 dB from 40 to 50 GHz with typical isolation of 29 dB from 18 to 40 GHz and 30 dB from 40 to 50 GHz.
Mini-Circuits’ model EP2-561+ is a two-way, 0-deg. power splitter/combiner fabricated with GaAs IPD technology for applications from 12.0 to 43.5 GHz, including 5G and radar systems. Supplied in a 2 × 2 mm surface-mount-technology (SMT) housing, the 50-Ω power splitter/combiner has full-band VSWR of 1.70:1 or better at all ports. Insertion loss (above the 3 dB split) is typically 1.1 dB from 12 to 24 GHz, 1.3 dB from 24 to 30 GHz, and 1.4 dB from 30.0 to 43.5 GHz. Isolation is typically 15 dB from 12 to 24 GHz, 23 dB from 24 to 30 GHz, and 16 dB from 30.0 to 43.5 GHz. The splitter/combiner provides outstanding amplitude and phase balance, with typical full-band amplitude unbalance of 0.2 dB or better and typical full-band phase unbalance of 1.7 deg. or better. The SMT MMIC handles as much as 0.5 W power as a splitter or combiner and has an operating temperature range of -55° to +105°C.
PMI Model No. PIQ-85M18G-36020-CD-2 is a vector modulator covering the frequency range of 85 MHz to 18 GHz. This unit provides an attenuator resolution of 0.1 dB and a phase shift resolution of 0.8°.
