MMD Monitor/Quartztek was founded in 1994 by Rodney M. Mills as a full service stocking manufacturer of Frequency Control Devices. Since then, MMD has developed into a service oriented technology company, driven by a knowledgeable management team and a dedicated staff committed to complete customer satisfaction. Headquartered in Rancho Santa Margarita, California, USA, MMD Monitor/Quartztek quickly established a reputation for service in the high volume, low cost segment of the frequency control industry. In 2002, MMD’s acquisition of Monitor Products and Quartztek, strengthened its position in the high stability, high performance oscillator arena, as well as in the military marketplace. Monitor Products had been a QPL qualified technology leader in the high stability segment of the frequency control market, manufacturing custom TCXOs and high accuracy OCXOs. Monitor Products was also (QPL) qualified to MIL-PRF-55310.
