YIG Replacement Oscillators-YRO
APA Wireless Patent Pending YRO™ series of “yig replacement oscillators” are simply the widest band, lowest noise vco’s available anywhere. Covering over half a GHz of bandwidth, these fundamental mode devices offer 10dB lower phase noise than anything on the market. Operating over the full industrial temperature range, these vco’s offer outstanding phase noise, ultra low pulling and pushing, with high immunity to vibration and phase hits. Current technology offers frequencies through 4 GHz, with higher frequencies (through X-Band) available in the near future.
