Abstract :
Monolithic slot antenna coupled Schottky-collector resonant tunnel diode (SRTD) oscillator arrays have been fabricated and tested. Earlier we have reported oscillators with oscillation frequencies to 200 GHz. Here we report recent results which indicate oscillation frequencies to 650 GHz for a 64-element monolithic array. To our knowledge this is the highest oscillation frequency for a monolithic oscillator. Additionally, both the 28 /spl mu/W output power of the 310 GHz array and the associated 440 W/cm/sup 2/ power density represent records for RTDs operating in this frequency range.
