A small-sized Integrated Radio Frequency Type Repeater includes first and second Service (transmitting) Antennas, a Junction circuit part with RF type (200) which plays the role of relay, a Shield Box (400) which protects the first and second Service Donor (receiving) Antennas (310, 320) and a Junction circuit part (200) installed inside of the same body. (Cover) (500). The first Service (transmitting) Antenna (110) and the first Donor (receiving) Antenna (310) attached to opposite sides of the Shield Box (400) and the second Service Antenna (120) is separated from the first Service (transmitting) Antenna (110) between the inside of Cover (500) and the first Service (transmitting) Antenna (110), and the second Donor (receiving) Antenna (320) is installed to be separated from the first Donor (receiving) Antenna (310) between the inside of the Cover (500) and the first Donor (receiving) Antenna (310). The Repeater makes good output waveform to transmit even in a state of low isolation margin including minimization of Oscillation volume due to delay reduction of Repeater by application of RF type which possible to use of Filter with low delay, not IF type which used SAW Filter or Digital Filter with a relatively high delay, and it takes effect to expand so much service scope by improvement of output gain with this.
