The UTC L8602 is a programmable low power depletion mode

FET bias and mixer controller intended primarily for satellite Low

Noise Blocks (LNBs).

Designed to provide system flexibility the UTC L8602 can be

programmed to bias six low noise amplifier (LNA) stages or four

LNA and two active mixer stages, allowing the UTC L8602 to be

used in several system designs.

Combining

an

advanced

IC

process

and

packaging

techniques, the UTC L8602 helps minimize power consumption,

component cost and PCB area whilst enhancing overall reliability.



FEAT U RES

* Low quiescent supply current, 1.6mA typical

* Six stage FET bias controller, two configurable as mixer stages

* Operating range of 3.0V to 8.0V

* Amplifier FET drain voltages set at 2.0V, mixer drain voltage set

at 0.25V

* Amplifier FET drain current selectable from 0 to 15mA, mixer

current from 0 to 7.5mA

* Switchable FET’s for power management

* FET drain voltages and currents held stable over temperature

* FETs protected against overstress during power-up and

power-down.

* Internal negative supply generator allowing single supply

operation (available for external use)

* Low external component count
