ADL5353

2200 MHz to 2700 MHz Balanced Mixer, LO Buffer, IF Amplifier, and RF Balun

Analog Devices 

The performance of this amplifier is critical in achieving a high

intercept passive mixer without degrading the noise floor of the

system. This is a critical requirement in an interferer rich environ-

ment, such as cellular infrastructure, where blocking interferers can

limit mixer performance. The bandwidth of the intermodulation

performance is somewhat influenced by the current in the LO

amplifier chain. For dc current sensitive applications, it is per-

missible to reduce the current in the LO amplifier by raising the

value of the external bias control resistor. For dc current critical

applications, the LO chain can operate with a supply voltage as

low as 3.3 V, resulting in substantial dc power savings.

ADL5353

In addition, when operating with supply voltages below 3.6 V, the

ADL5353 has a power-down mode that permits the dc current to

drop to <200 μA.

All of the logic inputs are designed to work with any logic family

that provides a Logic 0 input level of less than 0.4 V and a Logic 1

input level that exceeds 1.4 V. All logic inputs are high impedance

up to Logic 1 levels of 3.3 V. At levels exceeding 3.3 V, protection

circuitry permits operation of up to 5.5 V, although a small bias

current is drawn.

All pins, including the RF pins, are ESD protected and have been

tested to a level of 1500 V HBM and 500 V CDM.
