Transmission/reception directional filter (T/R cell)

摘要

According to the invention, a Wilkinson divider is used for implementing a filter which is very small, can be implemented technologically simply and is provided especially for projectile fuzes, such that the free limbs, which are connected via a load-compensating resistor, of two quarter-wave lines which are connected together at a junction point are connected to the reference electrode on the one hand via the transmission oscillator and on the other hand via the reception diode, while the antenna which is common to both devices (oscillator and diode) is connected to the junction point of the two quarter-wave lines.
