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.
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.

Product Description The 16 bands high power stationary signal blocker covers and blocks band frequencies of cellular phone,WIFI,Lojack,VHF&UHF radio.With the stationary type design,the signal blocker comes with a high output power,for supporting multiple signals blocking and a coverage that ranges from 2 meters to 50 meters. As a stationary signal blocker,it has an ability to keep working continually inside of a building or even in a vehicle (with car charger)You donâ??t have to take the problem of heat dissipation into your account,due to 2 cooling fans keep running inside to deal with the problem.
