GENERAL DESCRIPTION
The AD8342 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 inter-
modulation distortion and noise figure.
The AD8342 provides a typical conversion gain of 3.7 dB with
an RF frequency of 238 MHz. The integrated LO driver presents
a 50 Ω input impedance with a low LO drive level, helping to
minimize the external component count.
The differential high impedance broadband RF port allows for
easy interfacing to both active devices and passive filters. The
RF input accepts input signals as large as 1.6 V p-p or 8 dBm
(relative to 50 Ω) at P
1dB
.
The open-collector differential outputs provide excellent bal-
ance and can be used with a differential filter or IF amplifier,
such as the AD8369 or AD8351. These outputs can 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, the outputs may swing ±2 V differentially.
The AD8342 is fabricated on an Analog Devices proprietary,
high performance SiGe IC process. The AD8342 is available in a
16-lead LFCSP. It operates over a
−
40°C to +85°C temperature
range. An evaluation board is also available.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
