VVA1 VVA2 3 GHz Variable Gain LNA with Integrated W Driver Amplifier Data Sheet ADL5246 FEATURES GENERAL DESCRIPTION RF output frequency range: 0.6 GHz to 3 GHz The ADL5246 is a high performance, low noise variable gain Output IP3: 37 dBm at 2.2 GHz amplifier (VGA) optimized for multistandard base station receivers Output P1dB: 28 dBm at 2.2 GHz and point to point receive (Rx) and transmit (Tx) applications. The Noise figure of input amplifier: 1 dB at 2.2 GHz low noise figure and excellent linearity performance allow the Maximum gain: 31.5 dB at 2.2 GHz device to be used in a variety of applications. Voltage variable attenuation range: 45 dB The device consists of a low noise amplifier, a high linearity 0 V to 3.3 V attenuation control range VGA, and a W output driver stage. The variable attenuator Integrated bypass switch for low noise VGA networks are optimized to provide high linearity performance Matched 50 input stage over the 45 dB gain control range. Gain is set using a unipolar 3.3 V to 5 V single supply control voltage from 0 V to 3.3 V. The output stage of the ADL5246 32-lead, 5 mm 5 mm LFCSP package is an externally tuned W driver amplifier, which allows the device to be optimized anywhere between the 0.6 GHz to 3 GHz APPLICATIONS range, with an average tuning bandwidth of 200 MHz wide. An Multistandard radio receivers external filter can be used between the VGA and the final driver Point to point Rx and Tx amplifier. The ADL5246 can be biased between 3.3 V and 5 V to Instrumentation trade off between performance and power consumption. Military and aerospace The ADL5246 is fabricated on an advanced GaAs process. The device is available in a 32-lead, RoHS compliant, 5 mm 5 mm LFCSP and thermally rated to operate over the 40C to +105C temperature range.
