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.) /@Df = ±600 kHz

RSSI output dynamic range: 83 dB

• CR phase shifter is adopted.
