FET BIAS CONTROLLER WITH POLARISATION

SWITCH AND TONE DETECTION

ISSUE 1 - OCTOBER 1998

ZNBG3113

ZNBG3114

DEVICE DESCRIPTION

Drain current setting of the ZNBG3113/14 is

user selectable over the range 0 to 15mA, this

is achieved with addition of a single resistor.

The series also offers the choice of drain

voltage to be set for the FETs, the 3113 gives

2.2 volts drain whilst the 3114 gives 2 volts.

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 a

resistorthedevicesprovide drainvoltageand

current control for three 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.

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.

The ZNBG3113/14 includes bias circuits to

drive up to three external FETs. A control

input to the device selects either one of two

FETs as operational, the third FET is

permanently active. This feature is

particularly used as an LNB polarisation

switch. Also specific to LNB applications is

the 22kHz tone detection and logic output

feature which is used to enable high and low

band frequency switching.

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 1V.

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 facility to control the tone switching

delay is provided. This allows the rejection

of other lower frequency tones tat may be

present in multiple LNB applications.

The ZNBG3113/14 are available in QSOP20

for the minimum in device size. Device

operating temperature is -40 to 70°C to suit

a wide range of environmental conditions.
