CLC5506IM

Product Summary

The CLC5506IM 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 CLC5506IM allows designers to compensate for manufacturing component tolerances and temperature variations in receiver front ends. Maximum amplifier gain is set at 26dB . A three line MICROWIRE serial interface allows 16dB of attenuation from the max gain setting in precise 0.25dB steps. The CLC5506IM 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 possible to drive transformers allowing designers the ability to match a wide variety of transmission lines. The output amplifier has excellent output drive with low distortion. Digital control of the CLC5506IM is accomplished using MICROWIRE Interface. Data Out and a Load Enable are incorporated so that more than the CLC5506IM/channel may be programmed per system. The CLC5506IM 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 50W system, the third-order output intercept point is +22dBm at nominal gain of 18dB at 25℃. The CLC5506IM operates over the industrial temperature range of 40℃ to +85℃.
