F2255 Datasheet Voltage Variable RF Attenuator 1MHz to 3000MHz FEATURES GENERAL DESCRIPTION Low Insertion Loss: 1.1dB 500MHz The F2255 is a low insertion loss Voltage Variable RF Typical / Min IIP3: 60dBm / 46dBm Attenuator (VVA) designed for a multitude of wireless Typical / Min IIP2: 98dBm / 74dBm and other RF applications. This device covers a broad 33dB Attenuation Range frequency range from 1MHz to 3000MHz. In addition Bi-directional RF ports to providing low insertion loss, the F2255 provides +36dBm Input P1dB compression excellent linearity performance over its entire voltage VMODE pin allows either positive or negative control and attenuation range. control response The F2255 uses a single positive supply voltage of Linear-in-dB attenuation characteristic 3.15V to 5.25V. Other features include the VMODE pin Supply voltage: 3.15V to 5.25V allowing either positive or negative voltage control V range: 0V to 3.6V using 5V supply CTRL slope vs attenuation and multi-directional operation +105C max operating temperature meaning the RF input can be applied to either RF1 or 3mm x 3mm, 16-pin QFN package RF2 pins. Control voltage ranges from 0V to 3.6V using either positive or negative control voltage slope. DEVICE BLOCK DIAGRAM COMPETITIVE ADVANTAGE The F2255 provides extremely low insertion loss and superb IP3, IP2, Return Loss and Slope Linearity across the control range. Comparing to competitive VVAs this Control device is better as follows: Operation down to 1MHz Insertion Loss 500MHz: 1.1dB RF2 RF1 Maximum Attenuation Slope: 33dB/Volt Minimum Output IP3: 35dBm Minimum Input IP2: 74dBm High Operating Temperature: +105C ORDERING INFORMATION APPLICATIONS Tape & 0.9 mm height Base Station 2G, 3G, 4G Reel package Portable Wireless Repeaters and E911 systems Digital Pre-Distortion F2255NLGK8 Point to Point Infrastructure Public Safety Infrastructure RF product Line Green Satellite Receivers and Modems WIMAX Receivers and Transmitters PART MATRIX Military Radios covering HF, VHF, UHF RFID handheld and portable readers IIP3 RF Freq Range Insertion Loss Pinout Part (MHz) (dB) Compatibility Cable Infrastructure (dBm) Wireless LAN F2250 50 - 6000 1.4 (at 2GHz) +65 RFMD Test / ATE Equipment F2255 1 - 3000 1.1 (at 500MHz) +60 F2258 50 - 6000 1.4 (at 2GHz) +65 Hittite 2018 Renesas Electronics Corporation 1 May 7, 2021 V MODE V DD V CTRL F2255 Datasheet Voltage Variable RF Attenuator 1MHz to 3000MHz ABSOLUTE MAXIMUM RATINGS Parameter / Condition Symbol Min Max Units V to GND V -0.3 5.5 V DD DD VMODE to GND VMODE -0.3 Minimum ( VDD, 3.9 ) V V to GND V = 0V to 5.25V V -0.3 Minimum ( V , 4.0 ) V CTRL DD CTRL DD RF1, RF2 to GND VRF -0.3 0.3 V RF1 or RF2 Input Power applied for 24 hours maximum PMAX24 30 dBm (VDD applied 2GHz and Tc=+85C) RF1 or RF2 Continuous Operating Power PMAX OP See Figure 1 dBm Maximum Junction Temperature T +150 C JMAX Storage Temperature Range TST -65 +150 C Lead Temperature (soldering, 10s) T +260 C LEAD ESD Voltage HBM (Per ESD STM5.1-2007) VESDHBM Class 2 ESD Voltage CDM (Per ESD STM5.3.1-2009) VESDCDM Class C3 FIGURE 1: MAXIMUM OPERATING RF INPUT POWERS VS.
