SMR-5550i Microwave Receiver

SMR-5550i Microwave Receiver

The SMR-5550i meets the need for a low-cost, high-performance microwave receiver. The receiver offers all the necessary features for high data rate PCM/TDM reception while maintaining high pulse fidelity for RADAR interception. The SMR-5550i electrical design features the low group delay distortion, low phase noise characteristics and high dynamic range necessary in today’s demanding signal environments. Through the use of state-of-the-art commercial components coupled with a high volume production line, the SMR-5550i sets a new standard for performance-to-cost value in microwave/mm wave signal reception.
