ABSTRACT:
A broadband Impatt diode amplifier for microstrip includes a two-section quarter wavelength impedance transformer. Since the width of one transformer section exceeds a half wavelength, spurious mode resonance is suppressed using a longitudinal slot with an absorbing resistor or by offsetting the transformer sections. A compact configuration combines the power of two microwave diodes over a broad frequency range.
