Gain Trim Amplifier (GTA)
General DescriptionThe CLC5506isa low-noise amplifier with programmable
gainforusein cellular base stations, WLL, radarand RF/IF
subsystems where gain-controlis requiredto increasethe
dynamic range. The CLC5506 allows designersto compen-
satefor manufacturing component tolerancesand tempera-
ture variationsin receiver front ends. Maximum amplifier
gainissetat 26dB.A three-line MICROWIRE serial inter-
face allows 16dBof attenuation fromthe max gain settingin
precise 0.25dB steps.
The CLC5506 usesa differential input and output, allowing
large output swingson asingle5V rail.The differential outputwell suitedfor impedance matching networks drivingSAW
filtersor directly driving differential input analogto digital
converters (ADC).The differential output also makesit pos-
sibleto drive transformers allowing designersthe abilityto
matcha wide varietyof transmission lines.The output ampli-
fierhas excellent output drive withlow distortion.
Digital controlofthe CLC5506is accomplished usingMI-
CROWIRE Interface. DataOutanda Load Enableare incor-
poratedsothat more than one CLC5506/channel maybe
programmedper system.
The CLC5506 maintainsa 600MHz performance bandwidth
overits entire gain and attenuation range from +10dBto
+26dB. Gain controlis dividedinto64 equalstepsof 0.25dB
andis dB-linear. Output driveand distortion performanceare
excellent;Ina 50Ω system,the third-order output intercept
pointis +22dBmat nominal gainof 18dBat 25˚C. The
CLC5506 operates overthe industrial temperature rangeof
−40˚Cto +85˚C.
