WebbOne starter electrode and a primer (keep-alive) electrode for ion availability to keep the ignition voltage constant, for analog RC timers, voltage triggers, etc., or Two starter electrodes to make counters bidirectional or resettable W Trigger pentode, two starter electrodes and a primer electrode Numbers: Base type and serial number [6] WebbThe pentagrid was part of a line of development of valves that were able to take an incoming RF signal and change its frequency to a fixed intermediate frequencywhich was then amplified, and detected in the remainder of the receiver circuitry. The device was generically referred to as a frequency changeror just mixer. Contents 1Origins

This alternating polarity applied to the IF (or RF) creates the up/ down conversion. Therefore the LO signal must be strong enough to fully drive the diodes, ideally the LO signal is a square wave of current.
