DESCRIPTION

The µPC8139GR-7JH is a silicon microwave monolithic IC (SiMMIC) developed as a transceiver for Personal Handyphone System (PHS).

This IC is a highly integrated single chip, suitable for PHS, including a quadrature modulator, up converter, and AGC circuit for adjusting the output level in the transmitter block, a 2nd down converter and RSSI circuit in the receiver block, and a transistor for 2nd VCO.

This low power IC employs NEC’s proprietary bipolar process NESATTM IV (fT = 20 GHz) and also has a built-in power save function, which contributes to lowering power consumption of the RF block.

This IC is packaged in a small, thin 30 pin plastic TSSOP (225 mil).

FEATURES

• Low voltage operation, low current consumption

VCC = 2.7 to 4.0 V, ICC = 32.5 mA at transmitter, ICC = 4.8 mA at receiver, 3.2 mA/@VCC = 3 V at 2nd VCO block

• LPF is installed to suppress leakage of transmitter’s local (L01) harmonics.

Spurious within transmission band (LO1 × 7, 8): –55 dBc (MAX.)

• On-chip AGC circuit for adjusting the output level: GCR = 20 dB (MIN.) /@fRFout = 1906.55 MHz

• High-performance

Output level: PRFout = –13 dBm (TYP.) /@fRFout = 1906.55 MHz, VI/Q = 500 mVP-P (Differential phase)

Error vector magnitude: EVM = 1.0 rms (TYP.)

Adjacent channel leak power: Padj = –68 dBc (TYP.) /@∆f = ±600 kHz

RSSI output dynamic range: 83 dB

• CR phase shifter is adopted.

APPLICATION

• Digital cordless telephone: PHS

• PHS application equipment: PDA, PC card, etc.
