TQM879026 0.45-4 GHz 1/4W Digital Variable Gain Amplifier Product Overview The TQM879026 is a digital variable gain amplifier (DVGA) featuring high linearity and digital variable gain control in 0.5 dB step sizes. This DVGA integrates a gain block, a digital-step attenuator (DSA), and a high linearity -watt amplifier into a compact 4x4 mm package. The internal 6- bit DSA provides a 31.5 dB gain control range and is TM 24 Pin 4x4 mm leadless SMT Package controlled with a serial periphery interface (SPI ). The individual stages are accessible to external ports to allow for optimization of the last stage amplifier for use in any 3GPP telecom band and also allowing other functional Key Features blocks to be added in-between the stages. 450-4000 MHz The TQM879026 features variable gain from 1 dB to 32 dB 32 dB Maximum Gain at 2140 MHz at 2.14 GHz, +42.5 dBm output IP3, and +24 dBm P1dB 31.5 dB Gain Range in 0.5 dB Steps while only consuming 174 mA current from a 5V supply. The module is available in a compact 24-pin 4x4 mm +42.5 dBm Output IP3 leadless SMT package. +24 dBm Output P1dB 1.6 dB Noise Figure TM 3-wire SPI Control DSA Tunable for any 3GPP telecom band Functional Block Diagram Applications Wireless Infrastructure Pin 1 Marking Small cell BTS Pre-5G / 5G Massive MIMO systems NC 1 18 NC TDD-based architectures NC 2 17 NC DSA In 3 DSA 16 Amp2 Out / V CC2 NC 4 15 LE 6-BIT Amp1 Out / V 5 14 SID CC1 SPI NC 6 13 CLK Backside Paddle RF/DC GND Ordering Information Top View Part No. Description TQM879026TR13 2500 pieces on a 13 reel TQM879026-PCB900 900 MHz Evaluation Board TQM879026-PCB2140 2140 MHz Evaluation Board Datasheet, Rev.
