CLC5506
Gain Trim Amplifier (GTA)
General Description
The CLC5506 is a low-noise amplifier with programmable
gain for use in cellular base stations, WLL, radar and RF/IF
subsystems where gain-control is required to increase the
dynamic range. The CLC5506 allows designers to compen-
sate for manufacturing component tolerances and tempera-
ture variations in receiver front ends. Maximum amplifier
gain is set at 26dB . A three-line MICROWIRE serial inter-
face allows 16dB of attenuation from the max gain setting in
precise 0.25dB steps.
The CLC5506 uses a differential input and output, allowing
large output swings on a single 5V rail. The differential output
is well suited for impedance matching networks driving SAW
filters or directly driving differential input analog to digital
converters (ADC). The differential output also makes it pos-
sible to drive transformers allowing designers the ability to
match a wide variety of transmission lines. The output ampli-
fier has excellent output drive with low distortion.
Digital control of the CLC5506 is accomplished using MI-
CROWIRE Interface. Data Out and a Load Enable are incor-
porated so that more than one CLC5506/channel may be
programmed per system.
The CLC5506 maintains a 600MHz performance bandwidth
over its entire gain and attenuation range from +10dB to
+26dB. Gain control is divided into 64 equal steps of 0.25dB
and is dB-linear. Output drive and distortion performance are
excellent; In a 50system, the third-order output intercept
point is +22dBm at nominal gain of 18dB at 25˚C. The
CLC5506 operates over the industrial temperature range of
−40˚C to +85˚C.
