M64886FP General Description
M64886FP Features
• Receiver
It is possible to construct double conversion system.
Built in 1st MIX for 1st IF which can respond up to 2.4 GHz band.
Built in 2nd MIX and LIMITTER and RSSI and Demodulator for 2nd IF.
Built in Expander and Speaker Amp for Audio signal.
• Transmission
Built in PA (Pout = 1dBm max) which can respond up to 2.4 GHz band.
It is possible to control level of power by external variable resistor.
Out put is differential type, it is need to connect to RF filter with a balun circuit.
Built in Microphone Amp and Compressor and IDC and Splutter Filter for Audio signal.
• Synthesizer
Built in Differential type VCO for TX and RX which can respond up to 1.2 GHz band.
Built in 2-multiple circuit which can respond up to 2.4 GHz band.
Built in 2-modulus prescaler which can respond up to 1.2 GHz band.
Built in current output type charge pump.
Built in B-E Colpitts type crystal oscillation for reference frequency.
• Current consumption
Stand by mode = PLL+VCO+ DBL+LO+MIX+IF = 28 mA Typ.
TX / RX mode (ID) = Stand by + PLL+VCO+DBL+PA = 55 mA Typ.
TX / RX mode (Talk) = TX / RX mode (ID) +AF+SP = 65 mA Typ.
Off mode = < 50 A
