ADL5367
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
environment, 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 permissible 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 ADL5367 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 up to 5.5 V, although a small bias
current is drawn.
