Wideband, Dual Rx Mixers  
with Integrated IF Amplifiers  
Data Sheet  
ADRF6658  
FEATURES  
GENERAL DESCRIPTION  
Wideband, dual-channel, active downconversion mixers  
Low distortion, fast settling, IF DGAs  
RF input frequency range: 690 MHz to 3.8 GHz  
Programmable baluns on RF inputs  
For RF = 1950 MHz, IF = 281 MHz, high linearity mode  
Voltage conversion gain, including IF filter loss:  
−5 dB to +26.5 dB  
Input IP3: 29 dBm at minimum DGA gain  
Input P1dB: 12 dBm at minimum DGA gain  
SSB NF: 13 dB at maximum DGA gain  
Output IP3: 40 dBm at maximum DGA gain  
Output P1dB: 19 dBm at maximum DGA gain  
Channel isolation: 52 dB  
Differential and single-ended LO input modes  
Differential IF output impedance: 100 Ω  
Flexible power-down modes for low power operation  
Power-up time after enabling channels: 100 ns, typical  
Programmable via a 3-wire serial port interface (SPI)  
Single 3.3 V supply  
The ADRF6658 is a high performance, low power, wideband,  
dual-channel radio frequency (RF) downconverter with  
integrated intermediate frequency (IF) digitally controlled  
amplifiers (DGAs) for wideband, low distortion base station  
radio receivers.  
The dual Rx mixers are doubly balanced Gilbert cell mixers  
with high linearity and excellent image rejection. Both mixers  
convert 50 Ω RF inputs to open-collector broadband IF outputs.  
Internal tunable baluns on the RF inputs enable suppression of  
RF signal harmonics and attenuation of out-of-band signals  
before the mixer inputs, reducing input reflections and out-of-  
band interference signals. A flexible local oscillator (LO)  
architecture allows the use of differential or single-ended LO  
signals.  
The dual-channel IF DGAs are based on the ADL5201 and  
ADL5202 and have a fixed, differential output impedance of  
100 Ω. The gain is adjustable over a 31.5 dB range with a 0.5 dB  
step size via the on-chip SPI, or through independent, 6-bit  
parallel ports that support latch functionality. Each channel,  
from the mixer inputs to the IF amplifier outputs, together with  
an LC interstage band-pass filter, achieves a maximum voltage  
conversion gain of 26.5 dB.  
High linearity mode: 440 mA  
Low power mode: 260 mA  
APPLICATIONS  
Cellular base stations and wireless infrastructure receivers  
(W-CDMA, TD-SCDMA, WiMAX, GSM, LTE, PCS, DCS, DECT)  
Active antenna systems  
PTP radio link down converters  
Wireless LANs and CATV equipment  
Fabricated with the Analog Devices, Inc., high speed SiGe  
process, the ADRF6658 is available in a compact, 7 mm ×  
7 mm, 48-lead LFCSP package, and operates over the −40°C to  
+105°C temperature range.
