GENERAL DESCRIPTION  
The AD8344 is a high performance, broadband active mixer. It  
is well suited for demanding receive-channel applications that  
require wide bandwidth on all ports and very low intermodula-  
tion distortion and noise figure.  
The open-collector differential outputs provide excellent  
balance and can be used with a differential filter or IF amplifier,  
such as the AD8369 or AD8351. These outputs may also be con-  
verted to a single-ended signal through the use of a matching  
network or a transformer (balun). When centered on the VPOS  
supply voltage, each of the differential outputs may swing  
2.5 V p-p.  
The AD8344 provides a typical conversion gain of 4.5 dB at  
890 MHz. The integrated LO driver supports a 50 Ω input  
impedance with a low LO drive level, helping to minimize  
external component count.  
The AD8344 is fabricated on an Analog Devices proprietary,  
high performance SiGe IC process. The AD8344 is available  
in a 16-lead LFCSP package. It operates over a −40°C to +85°C  
temperature range. An evaluation board is also available.  
The single-ended 50 Ω broadband RF port allows for easy  
interfacing to both active devices and passive filters. The RF  
input accepts input signals as large as 1.7 V p-p or 8.5 dBm  
(re: 50 Ω) at P1dB.
