A Military Research Institute—Broadband Transceiver System RF Front-End Integration

Background

A certain military-industrial unit is developing a new generation of tactical communication equipment, which needs to cover an ultra-wideband transceiver front end and requires components with high power handling capability, low noise, and anti-interference characteristics.

Challenges

· Traditional discrete components are large in size and have high insertion loss, and cannot meet the miniaturization needs of handheld/vehicle-mounted platforms.

· Military environments require compliance with GJB 151B electromagnetic compatibility and GJB 150A environmental tests (power, vibration, shock).

· It is necessary to simultaneously achieve transmit-receive isolation, harmonic suppression, and fast channel switching functions.

Solution

Noxinbo, in cooperation with this unit, designed a miniaturized wideband transceiver front-end module:

· Microstrip components integrating filters, circulators, and isolators

· Operating frequency covers C, X, and Ku bands, isolation ≥30dB, capable of withstanding 50W continuous wave power.

· Module has passed the -55℃ to 85℃ operational assessment and third-party testing.
