Abstract
A quadrature signal generator comprises a resistor-capacitor, RC, polyphase filter and an inductor compensation arrangement. The inductor compensation arrangement comprises a first inductor connected between the first and the third output terminals, and a second inductor connected between the second and fourth output terminals. The first and second inductors are arranged to compensate for a capacitive load on the output terminals when in use. A beamforming arrangement, a communication device and a base station are also disclosed.
