Title:
HIGH FREQUENCY EQUIPMENT
Document Type and Number:
Japanese Patent JP3763503
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent wave stoppage with a plug-in unit not detached.
SOLUTION: When an ATT plug-in unit 20 has been detached, a transistor TR1 is turned ON and a current is supplied to a pin diode PIN. Thus, impedance of the pin diode PIN becomes small, and the output of a first amplification part 11 is inputted through the pin diode PIN to a second amplification part 12. Thus, even when the ATT plug-in unit 20 is damaged or lost, an amplifier 10 will not stop wave generation.
