The TGA4947-SL is a compact SMT package with 30 dB channel to channel isolation up to 40 GHz. TGA4947-SL Dual Driver Isolation vs Frequency Vd = 7 V, Vc1 = 0.5 V, Vc2 = 0.25 V, Vc3 = 0.05 V, Idq1 = 45 ma, Idq2 = 52 ma, Idq3 = 90 mA 0 Isolation I Channel Isolation Q Channel -10 Isolation (dB) The TGA4947-SL consists of two channels of three high performance wideband amplifiers and integrated broadband bias tees assembled in a 16 x 10.5 x 3.6 mm package, requiring a minimum of off-chip components. A single TGA4947-SL placed between the MUX and Optical Modulator provides OEMs with a modulator driver surface mount solution. -20 -30 -40 -50 -60 -70 -80 The TGA4947-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation, high signal to noise ratio (SNR), high voltage drive capability (3 Vpp amplitude adjustable up to 9 Vpp), fast rise and fall times, low output jitter, and low input drive sensitivity (0.4 Vpp – 1 Vpp at Vout = 8Vpp). The TGA4947-SL finish is lead-free. RoHS compliant. Evaluation boards and bias boards are available upon request.
