摘要：
A consequence of impedance mismatch for components located in the front-end of a microwave radiometer is that the radiometer's brightness temperature calibration becomes frequency-dependent. This dependence can limit the bandwidth over which a particular calibration is valid and place restrictions on local oscillator drift.
