17 to 19 GHz QPSK Modulator
The CCM19001 is a Differential Drive Digital QPSK (Quadrature Phase Shift Keying) modulator operating across the 17.0 to 19.0 GHz frequency range. The modulator utilizes differential drive digital inputs (180º apart) to drive both of the bi-phase modulators (mixers) integrated into the assembly. The modulator is a combination of a matched pair bi-phase modulators, which are in quadrature (90º) to each other. It is modulated by switching polarities of the DC voltage controls in 4 different logic states ("0,0", "0,1", "1,0" & "1,1") for 4 phase states. The QPSK modulator provides constant amplitude, 90º vector: 0 (ref.), 90º, 180º, 270º and operates across the -55º to 85º C temperature range.

Five Channel Amplifier
TMS designed the Five Channel Amplifier specifically for a custom space application. Each independent channel used dedicated RF Input/Output and DC bias connections. Each channel's RF performance was tailored differently to meet the application requirements. All components were manufactured and screened per MIL-PRF-38534, Class K. Additionally, to meet mission requirements The top assembly was also tested for RF and DC parameters during MIL-STD-202 thermal cycling and random vibration environments. This effort required disciplined development, manufacturing and program management efforts to meet challenging mechanical and RF engineering requirements.
IQ Demodulator
TMS IQ Demodulators are fully space-qualified designs providing stringent phase and amplitude matching, and superior output third order intercept performance. To meet high LO and IF rejection requirements diplexers are used at the I and Q ports. All components and processing fully meet MIL-PRF-38534, Class K and MIL-DTL-28837. TMS can provide performance to meet most receiver system requirements, including single or moving LO frequencies and tight phase and amplitude matching. Customers can specify our designs for space, military, or commercial applications.
