The pentagrid

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.

However, the Ferranti company of Great Britain entered the valve business with the first known UK-produced pentagrid, the VHT4 , late in 1933 (though it must have been in development, and would certainly have existed as a prototype well before that time).

Did you know?

WebbThe pentagrid converter has, as the name implies, five grid structures. Its primary application is in superheterodyne receivers, where it is used as a combination local oscillator and mixer. In operation, the cathode, control grid, and screen grid are used as the essential elements of a "triode" tube with appropriate components to form an oscillator.

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.
