GENERAL DESCRIPTION
The ADL5350 is a high linearity, up-and-down converting
mixer capable of operating over a broad input frequency range.
It is well suited for demanding cellular base station mixer designs
that require high sensitivity and effective blocker immunity. Based
on a GaAs pHEMT, single-ended mixer architecture, the ADL5350
provides excellent input linearity and low noise figure without
the need for a high power level LO drive.
In 850 MHz/900 MHz receive applications, the ADL5350
provides a typical conversion loss of only 6.7 dB. The input IP3
is typically greater than 25 dBm, with an input compression
point of 19 dBm. The integrated LO amplifier allows a low LO
drive level, typically only 4 dBm for most applications.

The high input linearity of the ADL5350 makes the device an
excellent mixer for communications systems that require high
blocker immunity, such as GSM 850 MHz/900 MHz and
800 MHz CDMA2000. At 2 GHz, a slightly greater supply
current is required to obtain similar performance.
The single-ended broadband RF/IF port allows the device to be
customized for a desired band of operation using simple external
filter networks. The LO-to-RF isolation is based on the LO
rejection of the RF port filter network. Greater isolation can be
achieved by using higher order filter networks, as described in
the Applications Information section.
The ADL5350 is fabricated on a GaAs pHEMT, high performance
IC process. The ADL5350 is available in a 2 mm × 3 mm, 8-lead
LFCSP. It operates over a −40°C to +85°C temperature range.
An evaluation board is also available.
