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.
|
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).
Product Features:
- Frequency range – 8 – 2000 MHz (If you require a different frequency, see the description above.)
