Title: Apparatus for self-diagnostic of TX/RX RF path in a WLL system
Inventor: PARK JEONG SEOK
IPC: H04B17/40
Filed: 2002-03-26
Abstract: PURPOSE: An apparatus for self-diagnosing a transmission/reception RF(Radio Frequency) path in a WLL(Wireless Local Loop) system is provided to self-diagnose the transmission and reception RF path although a signal of a base station does not exist. CONSTITUTION: The first coupler(120) couples a transmission signal and a diagnosis signal generated by RF path diagnosis when a signal of a base station does not exist, and outputs the coupled signal. An up-converter(130) up-converts the output signal of the first coupler(120) into an RF. An HPA(High Power Amplifier)(140) amplifies the output signal of the up-converter(130). A front-end unit(150) transmits a transmission signal inputted through the HPA(140) to a transmission/reception antenna(160), and couples the transmission signal at a certain rate, and outputs the coupled signal. The front-end unit(150) couples the diagnosis signal and a reception signal, and outputs the coupled signal. A down-converter(170) down-converts the reception signal outputted from the front-end unit(150) into an IF(Intermediate Frequency). The second coupler(180) transmits the output signal of the down-converter(170) to a channel card assembly(110), extracts the diagnosis signal, and transmits the diagnosis signal to the first coupler(120). A path diagnosis unit(190) provides a continuous wave for the RF path diagnosis to the front-end unit(150), detects the strength of a coupling signal outputted from the front-end unit(150), and judges whether a transmission/reception RF path is abnormal.
