Overview:
The MRFA89 is a general-purpose buffer amplifier that offers high dynamic range.
At 500 MHz, the amplifier typically provides 20 dB gain, +20dBm P1dB +31.7 dBm OIP3, and 4.6 dB Noise at 75 mA current.
This broadband MMIC amplifier can be directly applied to various current and next generation wireless
technologies such as CDMA, W-CDMA, and LTE. In addition, the TQP369185 will work for other various
applications within the 8 to 2000 MHz frequency range.
All components on the board are optimized to operate in the 8 – 2000MHz range.
If it is required to amplify the signal below 8 MHz, then it is necessary to increase the capacitance of the capacitors C1 and C2 (0,1 – 1 uF), and increase L1 (1 – 10 uH).
If it is required to amplify the signal above 2000 MHz, then it is necessary to decrease the capacitance of the capacitors C1 and C2 (100 pF), and decrease L1 (10 – 47 nH).
