描述 Description

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 ? 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
