BGA7204 400 MHz to 2750 MHz high linearity variable gain amplifier Rev. 4 15 November 2016 Product data sheet 1. Product profile 1.1 General description The BGA7204 MMIC is an extremely linear Variable Gain Amplifier (VGA), operating from 0.4 GHz to 2.75 GHz. At minimum attenuation it has a gain of 18.5 dB, an output IP3 of 38 dBm and a noise figure of 7 dB. The attenuation range is 31.5 dB with an attenuation step of 0.5 dB. The gain control is offered through a digital parallel interface or a digital serial interface (SPI). The digital serial interface offers advanced features like reprogramming the attenuation curve and on-chip temperature monitoring. The interfaces can be combined to support response to fast fading. The serial interface can be used to pre-set the desired gain level, whereas the parallel interface can be used to select this gain setting in 0.15 s. It has been designed and qualified for the severe mission profile of cellular base stations, but its outstanding RF performance and interfacing flexibility makes it suitable for a wide variety of applications. The BGA7204 is housed in a 32 pins 5 mm 5 mm leadless HVQFN package. 1.2 Features and benefits High output IP3 of 38 dBm Attenuation range of 31.5 dB Output power at 1 dB compression of 21 dBm Noise figure of 7 dB at minimum attenuation Single 5 V supply Digital parallel and digital serial control (SPI) Programmable attenuation curve Temperature sensor ESD protection on all pins (HBM > 2 kV) Moisture sensitivity level 1 Compliant to Directive 2002/95/EC, regarding Restriction of Hazardous Substances (RoHS) 1.3 Applications IF and RF applications WiMAX and cellular base stations Cable modem termination systems Temperature compensation circuitsBGA7204 NXP Semiconductors 400 MHz to 2750 MHz high linearity variable gain amplifier 1.4 Quick reference data Table 1.
