P-I-N Tuned hybrid device

Conclusions Thus, described device allows to control ultra high frequencies amplitude in wave propagation direction in the range from –3,5 dB to –43 dB. This device may be used as controlled filter with fixed controlling current values; as a variable attenuator with fluent current changing; and as a switcher with extreme controlling current value. The device has profitable weight-size parameters. Described device has two important advantages, namely higher attenuation level and a simple construction as compared with previously known one.
