Title:
TWO-WAY AMPLIFIER PROVIDED WITH MEASUREMENT TERMINAL
Document Type and Number:
Japanese Patent JP3927047
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a two-way amplifier without the need for preparing another amplifier separately, provided with a measurement terminal capable of outputting an uplink signal with a sufficient level without stopping a downlink signal and capable of measuring a component or the like of a confluent noise included in the uplink signal at the same level as that in an actual operation.
SOLUTION: The two-way amplifier is configured to include: an uplink signal amplifier unit 4; a downlink signal amplifier unit 5; a switch 7; and the measurement terminal 8 connected to the switch 7, the switch 7 is placed between the uplink signal amplifier unit 4 and a branching filter 3a at an output of an uplink signal and can switch the uplink signal amplified by the uplink signal amplifier unit 4 as to whether the uplink signal is to be outputted from an input output terminal 2a at the uplink signal output side or outputted from the measurement terminal 8.
