Ex-2 Wireless Mic

The high-frequency module is used exclusively for uhf wireless mic. With audio circuit, transmitting module (tx) could be made into a complete wireless speaker or belt-pack transmitter. Receiving module (rx) consists of noise amplification, one time frequency mixing, twice mixing, local oscillation, mcu frequency control and other functions. With audio circuit, it could be made into a complete wireless mic receiver. By applying d2008 directly, factories could simplify design and production of uhf wireless mic, and adopt the module easily in mining industry and electronic consumer system equipments.

D2009 may be applied in low-cost uhf and vhf wireless mic. With multiple frequency points pll, it may replace widely used single frequency point crystal in the market, and be easily embedded in wireless voice transmission and amplification in mining industry and electrical consumer systems. Together with audio circuit, transmitting module (tx) may be made into a complete wireless speaker or belt-pack transmitter. The receiving module (rx) is characterized by noise amplification, frequency mixing, local oscillation, mcu frequency control and other functions. Together with audio circuit, it may be made into a complete wireless mic receiver.
