Honeywell has a world class reputation for issues related to High Power Microwave design and test, and has invested heavily in facilities for the design and testing of complex waveguide equipment.
Honeywell has the following test facilities for high power testing of microwave devices and equipment:
- 1kW pulsed at 1 – 2.5GHz,
- 2 x 400W CW at 1 – 2.2GHz
- 200W CW at 10 – 14GHz
- 200W CW at 18 – 23GHz
- 200W CW at 27 – 39GHz
L-Band Facilities
- 1000MHz to 2500MHz coverage
- Single channel testing to 1kW peak power
- Dual channel testing to 800W peak power/channel
- Typical pulsed signal of 40ms width at 1.5kHz prf
- ‘Free electron’ seeding source using Strontium 90 beta emitter (~290MBq)
- Detection systems
- Phase nulling
- Third harmonic
- System verification samples
- 3-section bandpass filters
- Coaxial stripline (parallel-plate)
- 2 vacuum chambers available – typical working pressure < 8 x 106 mbar
- Temperature control typically -40ºC to +80ºC
Ku-Band Facilities
- 13GHz to 14GHz coverage
- Use of wave guide resonant ring provides maximum of 1kW peak power (dependent on DUT loss)
- Typical pulsed signal of 40µs width at 1.5 kHz prf
Ka-Band Facilities
- 35.75GHz operation (+/- 500MHz)
- Initial operation at 80W with intention to increase to 200W (HPA isolator dependent)
- Both CW and pulsed test signals possible, in principle
- 1-path, 2-port calibration possible (enhanced response)
- Temperature cycling capability over -25ºC to +90ºC (ambient pressure)
