GENERAL DESCRIPTION

The ADL5353 uses a highly linear, doubly balanced passive

mixer core along with integrated RF and local oscillator (LO)

balancing circuitry to allow for single-ended operation. The

ADL5353 incorporates an RF balun to provide optimal perfor-

mance over a 2200 MHz to 2700 MHz input frequency range

using high-side LO. The balanced passive mixer arrangement

provides good LO-to-RF leakage, typically better than −36 dBm,

and excellent intermodulation performance.

The balanced mixer core also provides extremely high input

linearity, allowing the device to be used in demanding cellular

applications where in-band blocking signals might otherwise

result in the degradation of dynamic performance. A high

linearity IF buffer amplifier follows the passive mixer core to yield a

typical power conversion gain of 8.8 dB and can be used with a

wide range of output impedances.

The ADL5353 provides two switched LO paths that can be used

in TDD applications where it is desirable to rapidly switch between

two local oscillators. LO current can be externally set using a

resistor to minimize dc current commensurate with the desired

level of performance. For low voltage applications, the ADL5353 is

capable of operation at voltages down to 3.3 V with substantially

reduced current. For low voltage operation, an additional logic

pin is provided to power down (<200 µA) the circuit when desired.

The ADL5353 is fabricated using a BiCMOS high performance

IC process. The device is available in a 5 mm × 5 mm, 20-lead

LFCSP and operates over a −40°C to +85°C temperature range.

An evaluation board is also available.
