12 / 26 page VCA8617 SBOS308B − AUGUST 2004 − REVISED NOVEMBER 2004 www.ti.com 12 TYPICAL CHARACTERISTICS: AVDD = 3V (continued) At TA = +25°C, load resistance = 1kΩ on each output to ground, unless otherwise noted. The input to the preamp (LNA) is single-ended; pre-amp gain is fixed at +20dB, fIN= 2MHz, PG = 01, ATN = 00, and the output from the VCA is differential, unless otherwise noted. 1100 1000 900 800 700 600 500 400 300 200 100 0 OUTPUT−REFERRED NOISE vs VCA CNTRL (ATN = 11, f IN =5MHz) VCA CNTRL (V) 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 PG = 01 PG = 00 PG = 11 PG = 10 80 70 60 50 40 30 20 10 0 INPUT−REFERRED NOISE vs VCA CNTRL (ATN = 11, f IN =2MHz) VCA CNTRL (V) 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 PG = 00 PG = 01 PG = 10 PG = 11 70 60 50 40 30 20 10 0 INPUT−REFERRED NOISE vs VCA CNTRL (ATN = 11, f IN =5MHz) VCA CNTRL (V) 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 PG = 11 PG = 10 PG = 01 PG = 00 60 55 50 45 40 35 30 25 20 NOISE FIGURE vs VCA CNTRL (ATN = 11, f IN =2MHz) VCA CNTRL (V) 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 PG = 00 PG = 01 PG = 10 PG = 11 55 51 47 43 39 35 31 27 23 17 NOISE FIGURE vs VCA CNTRL (ATN = 11, f IN =5MHz) VCA CNTRL (V) 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 PG = 00 PG = 01 PG = 11 PG = 10 1.25 1.20 1.15 1.10 1.05 1.00 INPUT−REFERRED NOISE (2MHZ, 2V VCNTRL) Gain Setting PG 00 PG 01 PG 11 PG 10 AT00 AT11 |
