Custom Designed Integrated Microwave Packages

e2v utilises a broad spectrum of technologies to produce a highly integrated RF Module for key defence applications. The following illustrate application-specific products.

X-Band TWTA Driver Amplifier Module

x-band power amplifier with integrated variable attenuator with 30 dB of attenuation in 0.5 dB steps. Output power 28 dBm with integrated precision video detectors allowing monitoring of input and output power levels. High input-output isolation (›60dB) and low mass (‹700g). Military airborne environment compatibility.

Ultra Low Noise UHF Sources

Surface Acoustic Wave Oscillators provide UHF output with very good close-to-carrier phase noise, together with defined temperature stability and long-term stability. Typically frequencies are in the range 600MHz to 1200MHz. Such oscillators are combined with power supplies, output amplification and switching to realise a compact, high performance, multiple-frequency source module.

To further enhance the electrical performance whilst under mechanical vibration, proprietary mechanical structures are used to isolate the SAW oscillators from the module housing. Oscillator module construction is compatible with military airborne environmental requirements.

  • Surface Acoustic Wave (SAW) oscillator technology
  • Ultra low RF Noise performance
  • Ultra low Phase Noise performance
  • Electronic switching between multiple, independent SAW Oscillator frequency channels (TTL interface)
  • UHF frequency band

X-Band power splitter

9 GHz RF amplifier and power splitter sourcing two pairs of balanced, isolated RF LO drive signals and two coupled power levels for coherent parallel receiving channels.

Upconverter/Multiplier

Upconversion module multiplying input S-Band signals to 35GHz. No significant fundamental, harmonics or spuriae on output signal.

KU-Band integrated RF Head

15 GHz circulator, limiter and low noise amplifier.
