  • High Reliability with RF ESD protection
  • +12 V Supply Voltage
  • 650 mA Operating Current Product Overview The TAT8804 is an ultra -linear, QFN GaAs amplifier MMIC intended for output stage amplification in CATV infrastructure applications. The device features a push - pull cascode design which provides flat gain along with ultra-low distortion, making it ideal f or use in CATV distribution systems requiring high output power capability. ESD protection is also provided at the output of the device. The TAT8804 draws approximately 650 mA from a single +12 V supply providing 21dB gain with excellent linearity. Users may adjust the bias current with external voltage enabling the TAT8804 to be used in applications such as doublers or for lower power system applications. The TAT8804 is packaged in an industry standard 40 pin 5 x 7 mm QFN package with exposed paddle (EP) beneath the device for thermal and electrical grounding. For applications requiring demanding VSWR tolerance at high input overdrive conditions, an EVB with level protection is available (TAT8804D1H-EBP).

Normally such overdrive is not a problem except when the output coax is not terminated. A full reflection at worst case phase may damage unprotected and overdriven amplifiers. An output protection scheme has been worked out for cases where customers cannot ensure that input RF overdrive and full reflections from the output coaxial network will not simultaneously occur. The scheme works by adding additional protection elements to the TAT8804 application circuit and in conjunction with the nominal 2.5 to 3.0 dB loss from output couplers, power inserters, and diplexer filters present in nearly all actives today. The circuit below protects the TAT8804 for an input +44 dBmV / ch FLAT (79 Ch. NTSC + 75 Ch. QAM at −6 dB offset) condition and a full reflection of any phase after a 3 dB output loss. The inclusion of additional protection elements to this application circuit results in a small degradation in output performance. Note: A new active protection circuit that responds to high VSWR is available from Qorvo that protects the device with minimal impact to IMD products at its full rated output. For more detailed discussion of this application, consult Qorvo Applications Engineering.
