| CATV 22 dB PUSH-PULL AMPLIFIER MC-7856 FEATURES * GALLIUM ARSENIDE ACTIVE DEVICES * LOW DISTORTION * LOW NOISE FIGURE (5.7 dB TYP at 860 MHz) * HIGH RELIABILITY (FIT = 125 at heat sink temperature of 100C, Report available) * INDUSTRY COMPATIBLE PACKAGE OUTLINE DIMENSIONS (Units in mm) PACKAGE OUTLINE 45.08 MAX 38.10.25 2.41 MAX 27.5 MAX 4.25 + 0.25 - 0.35 14.85 MAX 4.00.25 8.1 MAX 1 In 25.40.25 2.540.25 0.250.05 21.5 MAX 6-32 unc 2B VDD 5 9 Out 2378 Gnd DESCRIPTION The MC-7856 is a GaAs hybrid integrated circuit designed to be used as the input device in CATV applications up to 860 MHz. This unit has a minimum gain of 21.5 dB at 860 MHz, and because it is a GaAs device, it has lower distortion and lower noise figure. Reliability is assured by NEC's stringent quality and process control procedures. Devices are assembled and tested using fully automated equipment to maximize the consistency in part to part performance. 4.190.13 123 5 789 1.860.25 10.75 0.25 12.9 MAX 0.450.05 2.54 0.38 ELECTRICAL CHARACTERISTICS (TCASE = 30 C, VDD = 24 V, ZS = ZI = 75 ) SYMBOLS BW GA S Gf S11 Gain Gain Slope Gain Flatness Input Return Loss PART NUMBER PARAMETERS Frequency Range UNITS MHz dB dB dB dB dB dB dB dB dB dB dB dB dB dB dB mA dB dB 18.0 17.0 16.0 14.5 18.0 17.0 16.0 14.5 30 -60 -63 -63 220 5.3 5.7 -55 -55 -55 240 6.2 6.5 50 MHz 860 MHz MIN 50 21.5 0 MC-7856 TYP MAX 860 23.0 2.0 1.0 f = 860 MHz 50 to 860 MHz 50 to 860 MHz; Peak to Valley 50 to 160 MHz 160 to 320 MHz 320 to 640 MHz 640 to 860 MHz 50 to 160 MHz 160 to 320 MHz 320 to 640 MHz 640 to 860 MHz 50 to 860 MHz VOUT = +44 dBmV/ch VOUT = +44 dBmV/ch VOUT = +44 dBmV/ch CONDITIONS S22 Output Return Loss S12 CTB CSO XMod IDD NF Reverse Isolation Composite Triple Beat,110 Channels Composite Second Order, 110 Channels Cross Modulation, 110 Channels DC Current Noise Figure California Eastern Laboratories MC-7856 ABSOLUTE MAXIMUM RATINGS1 (TCASE= 30 C) SYMBOLS VDD VI TOP TSTG PARAMETERS Supply Voltage Input Voltage (Single Tone) Operating Temperature Storage Temperature UNITS V dBmV C C RATINGS 30 65 -30 to +100 -40 to +100 Note: 1.
