Qorvo TAT6254 & TAT7457 pHEMT RF Amplifiers

Qorvo TAT6254 and TAT7457 pHEMT RF Amplifiers are fabricated using high gain GaAs pHEMT technology to optimize performance and cost. These pHEMT RF Amplifiers provide excellent gain and return loss consistency inherent to the pHEMT process.

Features

TAT7457
- Gain, return loss, and bias externally adjustable
- On-chip active bias for consistent bias current and repeatable performance
- DC to 2000MHz bandwidth
- Low noise: typical NF < 2dB to 1000MHz
- Flexible 5V to 8V biasing
- IDD (5V) = 120mA typical in application circuit
- 19dB typical gain in application circuit
- +40dBm typical OIP3
- +61dBm typical OIP2
- +21dBm typical P1dB
- Low distortion: CSO -66 dBc, CTB -78 dBc (10 dBmV/ch at input, 80 ch NTSC flat)
- SOT-89 package

TAT6254
- Single 5V or 10V configuration
- Low noise 3.9pA/rtHz Equivalent Input Noise
- 19dBmV or 23dBmV/channel RF output at 55.25MHz
- 33dB AGC range, for -10dBm to +2dBm optical inputs
- Low power consumption (1.3W at 10V and 1.0W at 5V)
- Potentially eliminates the need for costly balun and directional coupler
- Linearity better than -63dBc CSO and CTB
- QFN20 package
