Mini-Circuits, a manufacturer of RF and microwave components, has introduced the HPCJ-Series, a line of 50 W LTCC surface-mount couplers designed for compact high-power RF applications. The HPCJ-Series is built using LTCC monolith construction and is offered in a 0.125" x 0.2" surface-mount footprint. The series supports coupling values from 20 dB to 30 dB and is specified for 50 W power handling. Key characteristics include low mainline loss, typically ≤0.15 dB, and directivity up to 30 dB. The devices are intended for applications where high power handling and small form factor are required.
The series includes multiple models covering specific frequency ranges and coupling configurations, including the HPCJ-03-422+, HPCJ-20-43+, and HPCJ-30-43+.
The HPCJ-03-422+ is a 3 dB, 90° hybrid splitter/combiner operating from 3200 to 4200 MHz. It provides 0.14 dB average insertion loss above 3 dB and 26 dB of isolation. The unit handles up to 50 W RF input power when used as a splitter and operates over a temperature range of -55 to +125°C. It is available in a 0.2" x 0.125" x 0.079" package. Listed applications include wireless infrastructure, 5G base stations in NR mid-band, satellite communications for C-band uplink and downlink, test and measurement, and radar systems.
The HPCJ-20-43+ is a directional coupler operating from 3300 to 4000 MHz with 20 dB coupling. It provides 0.09 dB mainline loss and 30 dB directivity, with 50 W RF input power handling and an operating temperature range of -55 to +125°C. The package measures 0.125" x 0.2" x 0.047". Applications listed include 5G Sub6, MIMO, n78 wireless infrastructure systems, microwave backhaul radio systems, radar systems, and satellite communications.
The HPCJ-30-43+ is a directional coupler covering 3300 to 4000 MHz with 30 dB coupling. It provides 0.11 dB mainline loss and 18 dB directivity. The device supports up to 50 W RF input power and operates over a temperature range of -55 to +125°C. It is offered in a 0.125" x 0.2" x 0.047" package. Applications listed include 5G Sub6, MIMO, n78 wireless infrastructure systems, microwave backhaul radio systems, radar systems, and satellite communications.
