DESCRIPTION
The
µPC2757TB and µPC2758TB are silicon monolithic integrated circuit designed as 1st frequency down-
converter for cellular/cordless telephone receiver stage.
The ICs consist of mixer and local amplifier.
The
µPC2757TB features low current consumption and the µPC2758TB features improved intermodulation. From these
two version, you can chose either IC corresponding to your system design. These TB suffix ICs which are smaller
package than conventional T suffix ICs contribute to reduce your system size.
The
µPC2757TB and µPC2758TB are manufactured using NEC’s 20 GHz fT NESAT™||| silicon bipolar process.
This process uses silicon nitride passivation film and gold electrodes. These materials can protect chip surface from
external pollution and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.
FEATURES
Wideband operation
: fRFin = 0.1 to 2.0 GHz, fIFin = 20 to 300 MHz
High-density surface mounting
: 6-pin super minimold package
Low current consumption
: ICC = 5.6 mA TYP. @
µPC2757TB
ICC = 11 mA TYP. @
µPC2758TB
Supply voltage
: VCC = 2.7 to 3.3 V
Minimized carrier leakage
: Due to double balanced mixer
Equable output impedance
: Single-end push-pull IF amplifier
Built-in power save function
