FET BIAS CONTROLLER

ISSUE 2 - JUNE 1998

DEVICE DESCRIPTION

The ZNBG series of devices are designed to

meet the bias requirements of GaAs and

HEMT FETs commonly used in satellite

receiver LNBs, PMR, cellular telephones etc.

with a minimum of external components.

With the addition of two capacitors and

resistors the devices provide drain voltage

and current control for a number of external

grounded source FETs, generating the

regulated negative rail required for FET gate

biasing whilst operating from a single

supply. This negative bias, at -3 volts, can

also be used to supply other external

circuits.

The ZNBG4000/1 and ZNBG6000/1 contain

four and six bias stages respectively. In

setting drain current the ZNBG4000/1 two

resistors allows individual FET pair control

to different levels, the ZNBG6000/1 two

resistors split control between two and four

FETs. This allows the operating current of

input FETs to be adjusted to minimise noise,

whilst the following FET stages can

separately be adjusted for maximum gain.

The series also offers the choice of drain

v ol t a ge t o b e s e t f or t he F E T s , the

ZNBG4000/6000 gives 2.2 volts drain whilst

the ZNBG4001/6001 gives 2 volts.

FEATURES

Provides bias for GaAs and HEMT FETs

Drives up to four or six FETs

Dynamic FET protection

Drain current set by external resistor

Regulated negative rail generator

requires only 2 external capacitors

Choice in drain voltage

Wide supply voltage range

QSOP surface mount package

4-137

These devices are unconditionally stable

over the full working temperature with the

FETs in place, subject to the inclusion of the

recommended gate and drain capacitors.

These ensure RF stability and minimal

injected noise.

It is possible to use less than the devices full

complement of FET bias controls, unused

drain and gate connections can be left open

circuit without affecting operation of the

remaining bias circuits.

In order to protect the external FETs the

circuits have been designed to ensure that,

under any conditions including power

up/down transients, the gate drive from the

bias circuits cannot exceed the range -3.5V

to 0.7V. Furthermore if the negative rail

experiences a fault condition, such as

overload or short circuit, the drain supply to

the FETs will shut down avoiding excessive

current flow.

The ZNBG4000/1 and ZNBG6000/1 are

available in QSOP16 and 20 pin packages

respectively for the minimum in devices size.

Device operating temperature is -40 to 70°C

to suit a wide range of environmental

conditions.
