Abstract:
1. Small-sized Integrated RF Type Repeater comprising: a first and second Service (transmitting) Antenna which plays the role of signal transmission; a junction circuit part which plays the role of relay; a first and second Donor (receiving) Antenna which plays the role of signal reception; and a Shield Box which protects and also plays the role of earth of the Junction circuit part, wherein the first and second Service (transmitting) Antenna, the junction circuit part, the first and second Donor (receiving) Antenna and the Shield Box are installed inside of the same body (Cover), and wherein the first Service (transmitting) Antenna and the first Donor (receiving) Antenna are formed to be attached to the opposite side of the Shield Box respectively, and the second Service Antenna is installed to be separated from the first Service (transmitting) Antenna between the inside of the Cover and the first Service (transmitting) Antenna, and the second Donor (receiving) Antenna is that installed to be separated from the first Donor (receiving) Antenna between the inside of the Cover and the first Donor (receiving) Antenna, and wherein the Junction circuit part comprises a first Duplex Filter which makes RF signal path separate; an RF transmitting part which makes output with performing of high power amplification after Filtering when RF signal which transmitted from Base Station is received via the first Duplex Filter; a second Duplex Filter which makes output to separate transmitting/receiving RF signal path, and transmits RF signal received from the RF transmitting part to the Terminal, and also transmit RF signal to the receiving part when RF signal is received from the Terminal; and a RF receiving part which makes output to the first Duplex Filter with performing of high power amplification after Filtering when RF signal which transmitted from Base Station is received via the second Duplex Filter, and wherein the transmitting part comprises a first LNA which amplifies RF signal with minimization of noise when RF signal is received from the first Duplex Filter; a first BPF which outputs after performing the Filtering function when RF signal is received from the LNA; a first Driving Amplifier which outputs after performing amplification of RF signal which is filtered via the first BPF; and a first HPA which outputs to the second Duplex Filter after performing High Power amplification of RF signal which is amplified via the first Driving Amplifier, and wherein the first BPF is embodied with DR (Dielectronic Resonator) Filter which has less than 0.7 μs of delay.
