NEC’s newest family of silicon and SiGe IF amplifiers offer DBS/Ku-Band receiver designers a wide choice of performance options. For designs in need of high gain, the UPC3225TB delivers 33.5 dB at 2.2 GHz. If low current is a concern, the UPC3227TB has an I_cc of just 4.8 mA at 5 V. Five devices are in the line-up, three of which are based on NEC’s newest 50 GHz UHS2 high speed SiGe process.
