An initial design for a 10 x 10 element heterodyne array was developed using 77 K, 1500-MHz photodiodes. Five PV-HgCdTe 150-MHz MHz photodiodes were then tested on a subassembly of a heterodyne matrix array structure with NEPs below 1.5 x 10 to the minus 19th power WHz measured out to 150 MHz. A thermal analysis was performed for 77 and 4.2 K matrix arrays with 150 and 1500 MHz operation to determine the cooler requirement for each case and the effect of the thermal loading on photomixer performance. A thermal mockup of the 77 K, 1500-MHz, 10 x 10 array was tested verifying the multi-cable thermal load analysis, the greater than 30-dB isolation between channels, and the greater than 24-hour operating time of the thermal mockup dewar.
