Microwave radio oscillator extends battery life in T1/E1 microwave radios

October 22, 2012 // By Jean-Pierre Joosting
The MRO Series is designed to extend the life of legacy analog and digital (T1/E1) microwave radios by replacing cavity-tuned oscillators which have been discontinued, obsoleted, or are otherwise no longer supported by original equipment manufacturers.

The MRO operates in the S, C and X frequency bands and features form-fit-function compatibility with older, manually-tuned cavity oscillators.

Unlike the cavity-tuned oscillators, the MRO has no warm-up time and no frequency drift since it is a phase-locked oscillator. Also, the MRO is serially-programmable to within 1 KHz of desired frequency which can then be manually tuned to a precise desired frequency of operation. The device includes an internal reference and non-volatile memory.

Custom units are available in 200 MHz bandwidths in the S, C and X-Band frequency ranges (2 to 8 GHz) in a connectorized package of just 3.05 x 2.02 x 1.62 inches. Additionally, EM Research will provide a customized mounting plate with each device for easy drop-in replacement of old cavity-tuned oscillators.
