TQM879028
TQM879028 is 0.6GHz - 4GHz 1/2W Digital Variable Gain Amplifier manufactured by Qorvo.
Overview The TQM879028 is a digital variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. This amplifier module integrates a gain block, a digital-step attenuator (DSA), and a high linearity ½ Watt amplifier into a pact 4 x 4 mm module. The internal 6-bit DSA provides a 31.5 d B gain control range in 0.5 d B steps, and is controlled with a serial periphery interface (SPITM). The individual stages are accessible to external ports to allow for optimization of the last stage amplifier for use in any 3GPP tele band and also allowing other functional blocks to be added in-between the stages. The TQM879028 features variable gain from 0.5 d B to 32 d B at 2.14 GHz, +44 d Bm output IP3, and +27.5 d Bm P1d B while only consuming 230 m A current from a 5 V supply. The module is available in a pact 24-pin 4 x 4 mm leadless SMT package. 24 Pin 4x4 mm leadless SMT Package Key Features - 600-4000 MHz - 32 d B Maximum Gain at 2140 MHz - 31.5 d B Gain Range in 0.5 d B Steps - +44 d Bm Output IP3 - +27.5 d Bm Output P1d B - 1.6 d B Noise Figure - 3-wire SPI Control Programming - Tunable for any 3GPP tele band Functional Block Diagram Pin 1 Marking 24 NC 23 DSA Out 22 NC 21 NC 20 Amp2 In 19 NC NC 1 NC 2 DSA In 3 NC 4 Amp1 Out / Vcc 5 NC 6 6-BIT SPI 18 NC 17 NC 16 Amp2 Out / Vcc 15 LE 14 DATA 13 CLK NC 7 Amp1 In 8 NC 9 SOD 10 NC 11 Vdd 12 Top View Backside Paddle RF/DC GND Applications - Wireless Infrastructure - Small cell BTS - Pre-5G / 5G Massive MIMO systems - TDD-based architectures Ordering Information Part No. Description TQM879028TR13 2500 pieces on a 13” reel TQM879028-PCB2140 2140 MHz Evaluation Board Datasheet, January 5, 2018 | Subject to change without notice 1 of...
