RF TRANSMISSION AND AMPLIFICATION SUBSYSTEMS
Signal Source & Power Amplifier Modules (JA-M)
The JA-M Series is a heavy-duty, field-proven portfolio of 30W and 50W RF subsystem modules engineered for high-reliability point-to-point communications, industrial telemetry links, and continuous-wave laboratory EMC testing. Available in both Active Signal Source Amplifier (built-in VCO) and Passive Power Amplifier (JN variant) architectures, each unit features a precision CNC-milled aluminum housing for exceptional thermal stability and vibration resistance across 700 MHz to 6500 MHz.
* Every module undergoes strict bench verification using Rohde & Schwarz, Agilent, and VNA test equipment to guarantee output power accuracy and VSWR ≤ 1.30. Custom frequency sub-bands, isolator integration, and connector options are available.
