• Manufacturer Part Number: adl5353
• Description: 2200 Mhz To 2700 Mhz Balanced Mixer, Lo Buffer, If Amplifier, And Rf Balun Adl5353
• Manufacturer: Analog Devices, Inc.

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.

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.
