SECOND MIXER + IF AMPLIFIER FOR DIGITAL CORDLESS TELEPHONES
The µPC8002 is a monolithic IC developed for use in digital cordless telephones. Its internal equivalent circuits comprise a double balanced mixer (DBM), IF amplifier circuit, and RSSI (Received Signal Strength Indicator) circuit. The µPC8002 can operate on a wide range of power supply voltages from 2.7 V to 5.5 V, and incorporates a power-off function, making it ideal for achieving low set power consumption.
The package is a 20-pin plastic shrink SOP (225 mil) suitable for high-density surface mounting.
FEATURES
• Low-voltage, low-consumption-current operation possible (VCC = 2.7 to 5.5 V, ICC = 3.4 mA at VCC = 3 V)
• Wide mixer input frequency range (fMIX = 250 MHz (TYP.) to 500 MHz (MAX.))
• Wide IF amplifier input frequency range (fIF = 8 MHz (MIN.) to 12 MHz (MAX.), 10.7 MHz (TYP.))
• High limiting sensitivity (SL = –100 dBm (TYP.))
• Wide RSSI dynamic range (DR = 85 dB (TYP.))
• On-chip power-off function
• Use of 20-pin plastic shrink SOP (225 mil) allows high-density surface mounting
