The F2251 from Renesas is a low loss Voltage Variable RF Attenuator (VVA) that operates from 50 to 6000 MHz. It has an attenuation range of 33.6 dB and an insertion loss of under 2.6 dB. The attenuator uses a single positive supply voltage of 3.15V to 5.25V. It provides excellent linearity performance over its entire voltage control and attenuation range. It also provides enhanced phase noise performance compared to its predecessor (F2250).
The attenuator is available in a 3 x 3 mm 16-VFQFPN package and is ideal for applications such as 2G, 3G, 4G base stations, portable wireless, repeaters and E911 systems, digital pre-distortion, military systems, JTRS radios, RFID handheld and portable readers, cable infrastructure, wireless LAN, and test/ATE equipment applications.
