Electronically Tuned Gunn Oscillators 18-140 GHz 6 (WG) V Series Features GaAs or InP Electronic Tuning to 4 GHz Excellent Linearity Output Power to 200 mW Small and Lightweight Optional Mechanical Tuning (5 or 28 Vde Temperature Controller Available Description These varactor tuned Gunn oscillators are designed to generate RF power in the 18 to 140 GHz range while allowing electronic tuning by suitably coupling an abrupt or hyberabrupt GaAs varactor with a Gunn diode (GaAs or InP) in a single cavity. Standard models achiev- ing 1% linearity, while producing 200 mW at 35 GHz and over 50 mW at 94 GHz, are used in FMCW radar transceivers, communica- tion links, collision avoidance radars, AFC loops and phase locked systems. Broadband models used for instrumentation and laboratory testing allow electronic tuning of over 4 GHz with center frequencies up to 100 GHz. Options with these oscillators include some mechanical tuning for course frequency adjustment, temperature controller to improve the frequency stability due to change in ambient temperature and an isolator to reduce the frequency pulling caused by changes in load VSWR. Environmental These devices are designed to meet the following conditions: Test MIL-STD Method Condition Temperature 202 102A -50C to +85'C 5 cycles, Cycle 4 hour per cycle Acceleration 202 212 11G, three mutually (Non-Operating) perpendicular axes Vibration High Freq.) 202 204B 10G Peak, 10-2000 Hz Maximum Ratings Storage Temp. -50C to +85C Operating Temp. ! -30C to +70C Notes: t. Units will operate from -30C to +70C although specifications listed above are guaranteed only between 0C and + 50C. Broader temperature units are available.

M/A-COM Ine. a 1011 Pawtucket Boulevard, Lowell, MA 01853 USA 6, When ordered with ferrite isolator, the output power will be reduced by the isolator loss. 7. When temperature controller is ordered, the units are stabilized at 55 + 2C and the output power is reduced by approximately 1.0 dB. 8. For most units, the varactor tuning voltage is from 0 to +25 Vdc (max.) with respect to ground. Some designs, though, require the tuning supply to be isolated from the case ground because the varactor voltage is referenced to the Gunn bias. 9. Modulation rate is 0-80 MHz. 10. Frequency stability is improved typically by a factor of 2 with temperature compensated units. a Telephone: 800-366-2266 5-7
