Yes. It was an early attempt to improve high-frequency operation.
The device had the usual emitter-base-collector construction, but with *two* base connections, one at either side.
In operation, a reverse bias applied to one of the base connections forced the current flow towards the other base, giving an artificially-narrow current path.
This reduced capacitances in the device, giving higher operating frequencies.
Concurrent, and later, developments gave greatly imrpoved perfomance from the conventional "triode" construction, so tetrode transistors became obsolete.
Be aware that the tetrode transistor is basically a triode (three-electrode) device, unlike the vacuum tube tetrode, which has four terminals and gives radically different characteristics from the triode vacuum tube.

Why you use tetrode instead of triode?
a tetrode is used when you need a screen grid tube, but a suppressor grid tube can't be used.OK, but the question was "why use a tetrode instead of a triode?"So, the answer...1. A tetrode has a higher voltage/power gain than a triode.2. A tetrode has less anode-grid feedback capacitance than a triode, and can operate in common-cathode radio frequency circuits without the neutralisation (or other corrective circuitry) that is needed by a triode.

How do you know if a transistor is a PNP or an NPN?
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
