ATR2733

The ATR2733 is designed as one kind of monolithically integrated L-band down-converter circuit that covers all functions of an L-band down-converter in a DAB receiver. And this device includes a gain-controlled amplifier, a gain-controlled mixer, an output buffer, a gain control block, a power-save function for the analog part, an L-band oscillator, and a complete frequency synthesizer unit.

Features of the ATR2733 are:(1)Supply Voltage: 8.5V; (2)RF Frequency Range: 1400 MHz to 1550 MHz; (3)IF Frequency Range: 150 MHz to 250 MHz; (4)Enhanced IM3 Rejection; (5)Overall Gain Control Range: 30 dB Typically; (6)DSB Noise Figure: 10 dB; (7)Gain-controlled Amplifier and L-band Mixer; (8)Power-down Function for the Analog Part; (9)On-chip Gain-control Circuitry; (10)On-chip VCO, Typical Frequency 1261.568 MHz; (11)Internal VCO Can Be Overdriven by an External LO.

The absolute maximum ratings of the ATR2733 can be summarized as:(1)Supply voltage:0.3 to +9.5 V;(2)RF input voltage: 750 mVpp;(3)Voltage at pin AGC: 0.5 to 6 V;(4)Voltage at pin TH:0.3 to +4.0 V;(5)Input voltage at pin TANK (internal oscillator overdriven): 1 Vpp;(6)Current at IF output: 4.0 mA;(7)Reference input voltage (diff.): 1 Vpp;(8)Control input voltage:0.3 to +9.5 V;(9)PLCK output current: 0.5 mA;(10)Junction temperature: 125 °C;(11)Storage temperature:40 to +125 °C.
