BGA7350 50 MHz to 250 MHz high linearity Si variable gain amplifier 24 dB gain range Rev. 1 21 December 2011 Product data sheet 1. Product profile 1.1 General description The BGA7350 MMIC is a dual independently digitally controlled IF Variable Gain Amplifier (VGA) operating from 50 MHz to 250 MHz. Each IF VGA amplifies with a gain range of 24 dB and at its maximum gain setting delivers 17 dBm output power at 1 dB gain compression and a superior linear performance. The BGA7350 Dual IF VGA is optimized for a differential gain error of less than 0.1 dB for accurate gain control and has a total integrated gain error of less than 0.4 dB. The gain controls of each amplifier are separate digital gain-control word, which is provided externally through two sets of 5 bits. The BGA7350 is housed in a 32 pins 5 mm 5 mm leadless HVQFN32 package. 1.2 Features and benefits Dual independent digitally controlled 24 dB gain range VGAs, with 5-bit control interface 50 MHz to 250 MHz frequency operating range Gain step size: 1 dB 0.1 dB 18.5 dB power gain Fast gain stage switching capability 17 dBm output power at 1 dB gain compression 5 V single supply operation with power-down control Logic-level shutdown control pin reduces supply current Excellent ESD protection at all pins Moisture sensitivity level 2 Unconditionally stable Compliant to Directive 2002/95/EC, regarding Restriction of Hazardous Substances (RoHS) 1.3 Applications Compatible with W-CDMA / WiMAX / LTE base-station infrastructure / multi carrier systems Multi channel receivers General use for ADC driver applicationsBGA7350 NXP Semiconductors 50 MHz to 250 MHz high linearity Si variable gain amplifier 1.4 Quick reference data Table 1.
