The EWG-1 type headphone is composed of FM radio ASIC D7088 and dual channel power amplifier integrated circuit D2822. The principle circuit is shown in the figure. The machine is unique in that it inserts a high-frequency amplifier into the antenna input circuit, which has high sensitivity and reliable operation.

Head-mounted radio headset circuit diagram
The high-frequency triode VT and the peripheral components L1, C1, L2, C3, etc. form a common-emitter high-frequency amplification 瞿贵荣电路, which amplifies the weak signal received by the antenna TX, and is coupled to the input selection consisting of C7, C8, and L3 via C4. Frequency network, then enter IC1 (D7088).
IC1 uses advanced low-IF technology to process the signal, thus eliminating the IF transformer, ceramic filter and antenna input tuning loop, and automatically searching for the radio using electrical tuning, eliminating the variable capacitance of the local oscillator level, greatly simplifying the periphery. Circuit.
