EEV CV6107 / BS510 S-band monitor diode

Size This valve measures 400x12mm overall (18mm across the heater/cathode terminal)

This is a monitor diode operating in the frequency range 2.5 to 6.5GHz. It is designed to be used in a suitable mount, the bandwidth and v.s.w.r. depending on the mount used.

Heater voltage (pre-heat) 6.3V
Heater voltage (operating) (see below)
Heater current 1.2A
Frequency range 2.5 to 6.5GHz
Max V.S.W.R. 1.5:1
Load resistance 68 ohms
Max peak input power 20kW
Max mean input power 18W
Max pulse length 15µs

The maximum diode life will be obtained if the heater voltage is reduced when the diode is operating with r.f. power input. The voltage should be 10% to 20% higher than the value at which the amplitude of the diode output begins to decrease.

The connections are (refer to main picture) heater/cathode: large terminal, heater (other end), 'collector': central section.
