GENERAL DESCRIPTION

The

ADL5336

consists of a pair of variable gain amplifiers

(VGAs) designed for cascaded IF applications. The amplifiers

have linear-in-dB gain control and operate from low frequencies to

1 GHz. Their excellent gain conformance over the control range

and flatness over frequency are due to Analog Devices, Inc.,

patented X-AMP® architecture, an innovative technique for

implementing high performance variable gain control.

Each VGA has 24 dB of gain control range. Their maximum gain

can be independently programmable over a 6 dB range via the

SPI. The VGAs can be cascaded to provide a total range of 48 dB.

When connected to a 50 Ω source through a 1:4 balun, the gain

is 6 dB higher. The second VGA has an SPI programmable input

switch that selects one of two external inputs.

When driven from a 200 Ω source or from a 50 Ω source through

a 1:4 balun, the noise figure (NF) for the composite amplifier is

6.8 dB at maximum gain. The output of each VGA can drive

100 Ω loads to 5 V p-p maximum.

Each VGA has an independent square law detector for autonomous,

automatic gain control (AGC) operation. Each detector setpoint

can be programmed independently through the SPI from −24 dBV

to −3 dBV in 3 dB steps. When both VGAs are arranged in AGC

mode and are programmed to the same setpoint, the composite NF

increases to 9 dB when backed off by 18 dB from maximum gain.

The

ADL5336

operates from a 5 V supply and consumes a typical

supply current of 80 mA. When disabled, it consumes 4 mA. It is

fabricated in an advanced silicon-germanium BiCMOS process and

is available in a 32-lead exposed paddle LFCSP package. Performance

is specified over a −40°C to +85°C temperature range.
