FEATURES I/Q Demodulator RF frequency 400 MHz to 6000MHz IIP3 +31 dBm IIP2 +60dBm Input P1dB +12dBm NF 13.2 dB @ 2.5GHz Voltage Conversion Gain of 4dB Quadrature demodulation accuracy Phase accuracy <0.5° Amplitude balance <0.25 dB LO Input –10 to +6 dBm Demodulation Bandwidth ~500 MHz I/Q Drive 2Vpp into 200Ω APPLICATIONS QAM/QPSK demodulator W-CDMA/CDMA/CDMA2000/GSM Point-to-(Multi)Point Radio WiMax/LTE GENERAL DESCRIPTION The ADL5380 is a high performance quadrature I-Q demodulator that covers an RF input frequency range from 400 MHz to 6 GHz. With a NF = 13dB, IP1dB = 12dBm and IIP3 = 31dBm at 2.5GHz, the demodulator offers good dynamic range suitable for the demanding infrastructure direct-conversion requirements. The differential RF inputs provide a well-behaved broad-band input impedance of 50Ω and should be driven from a 1:1 balun for best performance. Excellent quadrature accuracy is achieved using on-chip polyphase filters for LO quadrature generation. Over a wide range of local oscillator (LO) levels, excellent demodulation accuracy is achieved with phase and amplitude balances < 0.25 dB and < 0.5o, respectively. The demodulated in-phase (I) and quadrature (Q) differential outputs are fully buffered. The ADL5380 provides a typical voltage conversion gain of 4dB independent of differential load impedances as low as 100 Ω with a drive capability exceeding 2Vpp in to 200 Ω. The fully balanced design minimizes effects from 2nd order distortion. The leakage from the LO port to the RF port is <- 60dBc. Differential DC-offsets at the I and Q outputs are 60dBm. The ADL5380 operates off a 4.75V to 5.25V supply with a typical supply current of 200mA. The ADL5380 is fabricated using Analog Devices’ advanced Silicon-Germanium bipolar process and is available in a 24-lead exposed paddle LFCSP package. Performance is specified over a -40oC to +85oC temperature range. Rev. PrB Information furnished by Analog Devices is believed to be accurate and reliable.
