µPC2721, µPC2722
GENERAL PURPOSE L-BAND DOWN CONVERTER ICs
DESCRIPTION
The µPC2721/2722 are Silicon monolithic ICs designed for L-band down converter. These ICs consist of double
balanced mixer, local oscillator, local oscillation buffer amplifier, IF amplifier, and voltage regulator.
The packages are 8 pin SOP or SSOP suitable for high-density surface mount.
FEATURES
• Wide band operation fRF = 0.9 to 2.0 GHz
• Two products in IF output variation are prepared
µPC2721: Emitter follower output type = 50 Ω constant resistive impedance
µPC2722: Open collector output type = High impedance output dependent on external inductance.
• Single-end push-pull IF amplifier suppresses fluctuation in output impedance.
• Supply voltage: 5 V
• Low current consumption (µPC2721: ICC = 38 mA typ., µPC2722: ICC = 28 mA typ.)
• Packaged in 8 pin SOP or SSOP suitable for high-density mounting
