T K-715 0 12 CIRCUIT DESCRIPTION 1. Outline The TK-7150 is a VHF/FM transceiver designed to operate in the frequency range of 136 to 174MHz. Transmission out- put power is 50 watts. The maximum channel capacity is 128. The unit consists of receiver, transmitter, phase-locked loop (PLL) frequency synthesizer, and control circuits. 2. Receiver Circui[...]

T K-715 0 13 2-4. Audio Amplifier The recovered audio signal obtained from IC201 is ampli- fied and anti-aliasing filtered by IC712 (A/2), inputted to the AINR terminal of CODEC IC (IC713), and audio processed by DSP (IC710). The processed audio signal from AOUTR termi- nal of IC713 is amplified and filtered by IC716 (A/2) to a suffi- cient level. [...]
