T pad

Figure 1. Schematic circuit of a T-pad attenuator.
Figure 2.  A general L-section circuit with series impedance Z and shunt admittance Y.
Figure 3. A T-pad attenuator formed from two symmetrical L sections.  Because of the symmetry, R1 = R3 in this case.

The T pad is a specific type of attenuator circuit in electronics whereby the topology of the circuit is formed in the shape of the letter "T".

Attenuators are used in electronics to reduce the level of a signal. They are also referred to as pads due to their effect of padding down a signal by analogy with acoustics. Attenuators have a flat frequency response attenuating all frequencies equally in the band they are intended to operate. The attenuator has the opposite task of an amplifier. The topology of an attenuator circuit will usually follow one of the simple filter sections. However, there is no need for more complex circuitry, as there is with filters, due to the simplicity of the frequency response required.
