1 / 30 page  75Ω Voltage Variable Attenuator 5MHz to 3000MHz F2270 Datasheet 1 January 16, 2019 Description The F2270 is a 75Ω, low insertion loss voltage variable RF attenuator (VVA) designed for a multitude of wireless and other RF applications. This device covers a broad frequency range from 5MHz to 3000MHz. In addition to providing low insertion loss, the F2270 provides excellent linearity performance over its entire attenuation range. The F2270 uses a positive supply voltage of 3.3V or 5V. Other features include a VMODE pin allowing either a positive or negative voltage control slope versus attenuation and multi-directional operation where the RF input can be applied to either the RF1 or RF2 pins. The attenuation control voltage range is from 0V to 5V using either a 3.3V or 5V power supply. Competitive Advantage The F2270 provides extremely low insertion loss and superb IP3, IP2, return loss performance, and slope linearity across the control range. Compared to the previous state-of-the-art for silicon VVAs, this device provides superior performance: Operation down to 5MHz Insertion loss at 300MHz of 1.1dB Typical attenuation slope: 10dB/Volt Minimum OIP3 (maximum attenuation): +35dBm Minimum IIP2 (maximum attenuation, > 35MHz): +85dBm Typical Applications CATV/Broadband Applications Headend Fiber/HFC Distribution Nodes CATV Test Equipment Features Frequency range: 5MHz to 3000MHz Low insertion loss: 1.1dB at 300MHz Typical/Minimum IIP3 ≥ 50MHz: 62dBm / 46dBm Typical/Minimum IIP2 ≥ 50MHz: 98dBm / 77dBm Up to 35dB attenuation range Attenuation slope versus VCTRL: 10dB/Volt Bi-directional RF ports +36dBm input P1dB VMODE pin allows either positive or negative attenuation control response Linear-in-dB attenuation characteristic Nominal supply voltage: 3.3V or 5V VCTRL range: 0V to 5V using 3.3V or 5V supply -40°C to +105°C operating temperature range 3 × 3 mm, 16-VFQFPN package Block Diagram Figure 1.
