Microwave Low-pass Filter

Model No. MMP05
Feature

When the frequency spacing between channels is narrow, such as in cell phones, intermodulation distortion occurs if there is no linearity in the amplification of the circuit.

The waves generated by this distortion affect the adjacent channels.

When measuring this effect, it is necessary to keep the second and third harmonic wave of the measurement signal generator low. Keycom's microwave low-pass filter is an excellent filter for this purpose.
