RF Wideband Gain-Settable F1792 Downconverting Mixer Datasheet 400MHz to 3800MHz Description Features This document describes the specifications for the F1792 RF range: 400MHz to 3800MHz TM TM Wideband, Gain-Settable, Zero-Distortion Flat-Noise , RF to LO range: 400MHz to 3600MHz IF Downconverting Mixer. IF Range: 50MHz to 600MHz The F1792 offers very low power consumption with excellent 4 Gain Settings 11dB, 8dB, 5dB, 2dB linearity. In addition to this the F1792 has four dynamically 2 bit gain step control adjustable gain settings. The F1792 performance is exceptional Ideal for Multi-Carrier Systems across an extremely broad range of RF and IF frequencies. All of +35dBm OIP3 this makes it ideal for a myriad of applications including: TM Low Noise Figure at any gain setting via IDTs FlatNoise 2G/3G/4G/5G/Multimode Remote Radio Units technology Point to Point Wave Backhaul systems Z = 200 IF balanced, 50 RF, 50 LO single ended Broadband Repeaters All internally matched. Single BOM for all RF, LO and IF Public Safety Infrastructure frequencies Any radio system operating between 400MHz and 4000MHz 4 x 4 mm, 24-pin TQFN package Independent Path Standby mode 75 nsec settling for gain adjustment Competitive Advantage VCC = 3.3V, 462 mW, 373 mW (low power mode) F1792 offers maximum performance and flexibility at minimum power consumption. The unique and patented settable-gain feature allows it to be used in a very wide variety of radio card Band Performance Summary applications, even allowing for dynamic adjustment of gain to RF Frequency (MHz) 900 1900 2600 3500 maximize performance on the fly. The extremely wide RF and IF bandwidths are achieved using a fixed BOM, all RF matching is Gain (dB, max G11 setting) 11.0 10.8 10.3 9.0 internal to the device. The F1792 can function with as little as -6 Gain (dB, min G2 setting) 2.5 2.3 1.8 0.5 dBm LO power. It also features a channel shutdown mode for ease of integration into high order TDD systems.
