- このページには、製造中止（生産終了）となった製品の情報が記載されています。本ページに記載されている仕様および情報は、過去の参考情報です。
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 third-order intercept point (IP3O) 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 μs.
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 x 5 mm leadless HVQFN package.
