1 / 19 page  6-bit Digital Step Attenuator 400 to 4000 MHz F1953 Datasheet © 2022 Renesas Electronics Corporation 1 February 9, 2022 DESCRIPTION This document describes the specification for the F1953 Digital Step Attenuator. The F1953 is part of a family of Glitch-FreeTM DSAs optimized for the demanding requirements of communications Infrastructure. These devices are offered in a compact 4 x 4 mm QFN package with 50Ω impedances for ease of integration. COMPETITIVE ADVANTAGE Digital step attenuators are used in Receivers and Transmitters to provide gain control. The F1953 is a 6-bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (> +60dBm IP3I.) The device has pinpoint accuracy and settles to final attenuation value within 400ns. Most importantly, the F1953 includes Renesas’ Glitch-FreeTM technology which results in less than 0.5dB of overshoot ringing during MSB transitions. This is in stark contrast to competing DSAs that glitch as much as 10dB. Lowest insertion loss for best SNR Glitch-FreeTM when transitioning – won’t damage PA or ADC Extremely accurate with low distortion APPLICATIONS • Base Station 2G, 3G, 4G, TDD radio-cards • Repeaters and E911 systems • Digital Pre-Distortion • Point to Point Infrastructure • Public Safety Infrastructure • WIMAX Receivers and Transmitters • Military Systems, JTRS radios • RFID handheld and portable readers • Cable Infrastructure PART# MATRIX Part# Freq range Resolution / Range Control IL Pinout F1950 150 - 4000 0.25 / 31.75 Parallel & Serial -1.3 PE43702 PE43701 F1951 100 - 4000 0.50 / 31.5 Serial Only -1.2 HMC305 F1952 100 – 4000 0.50 / 15.5 Serial Only -0.9 HMC305 F1953 400 - 4000 0.50 / 31.5 Parallel & Serial -1.3 PE4302 DAT-31R5 FEATURES • Glitch-FreeTM, < 0.6dB transient overshoot • Spurious Free Design • 2.7 to 3.6 V supply • Attenuation Error < 0.5dB at 2GHz • Low Insertion Loss < 1.4dB at 2GHz • Excellent Linearity >+60dBm IP3I • Fast settling time, < 400ns • Serial or Parallel Interface 31.5dB Range • Stable Integral Non-Linearity over temperature • Low Power Consumption < 200µA • Integrated DC blocking capacitors • Drop-In replacement • 4 x 4 mm thin 20-VFQFPN package DEVICE BLOCK DIAGRAM ORDERING INFORMATION RF1 Bias VDD VMODE DEC D[5:0] 6 CLK SPI LE DATA RF2 F1953NCGI8 0.8 mm height package Green Industrial Temp range Tape & Reel RF product Line Glitch-FreeTM Glitch-FreeTM |
