NODE IC MHW 7222

The MHW7222 and MHW8222 are designed specifically for up to 860 MHz CATV systems as amplifiers in trunk and line extender applications. These amplifiers feature ion–implanted, arsenic emitter transistors and an all gold metallization system.

• Specified for 110/128–Channel Performance
• Broadband Power Gain — @ f = 40–860 MHz
Gp = 22 dB Typ @ 750 and 860 MHz
• Broadband Noise Figure
NF = 5.5 dB Typ — MHW7222
6.4 dB Typ — MHW8222
• Superior Gain, Return Loss and DC Current Stability with Temperature
• All Gold Metallization

High dynamic range optical receiver amplifier modules in a standard SOT115 package where the non-jacketed fiber has either no connector or has an FC/APC or SC/APC connector. The amplifier supply voltage pin and the photo diode bias voltage pin both connect to 5 V (DC). The modules have a mono mode optical input suitable for 1 290 nm to 1 600 nm wavelengths, a terminal to monitor the photo diode current and an electrical output having a characteristic impedance of 75Ω. Features ■ Excellent linearity ■ Low noise ■ Excellent flatness ■ Standard CATV outline ■ Rugged construction ■ Gold metallization ensures excellent reliability Applications CATV optical node systems operating in the 40 MHz to 870 MHz frequency range.
