DESCRIPTION
The
PC2721/2722 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
PC2721: Emitter follower output type = 50 constant resistive impedance
PC2722: 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 (
PC2721: ICC = 38 mA typ., PC2722: ICC = 28 mA typ.)
Packaged in 8 pin SOP or SSOP suitable for high-density mounting
