Extreme BW RF Amplifiers

We've developed 2 extremely wide bandwidth RF amplifiers, covering the frequency ranges from 5 KHz to 2 GHz and 5 KHz to 3 GHz. This amplifier was developed to provide high dynamic range amplification of communication signals starting from 5 KHz and up to 3 GHz. In addition to the Extreme Bandwidth RF amplifier, we've incorporated a design-adjustable equalizer at the amplifier input and an optional resistive power divider at the amplifier output, all integrated into the same package.

The typical performance of the Extreme BW RF Amplifier design is provided below:

Frequency Range: 5 KHz to 2 GHz Gain: 24 to 20 dB from 5 KHz to 2 GHz Noise Figure: 4.0 to 5.0 dB from 10 MHz to 2 GHz 1 dB Output Compression Point: 21 dBm typical Third Order Output Intercept Point: 35-37 dBm typical Input Voltage: +24 VDC (single voltage!) Input current: 100 mA typical Integrated Package Size: 1.9" L X 1.3" W X 0.4" H. This package includes input DC filter, input equalizer, and output resistive power divider Input equalizer slopes are customizable (0-12 dB slope across the band) Output resistive power divider can be "zeroed out" if not needed Options for +12 to +15 VDC inputs with additional DC-DC converter and DC filter Maximum RF input power: +13 dBm

We've taken quite a lot of data on the Extreme BW RF Amplifier. Some of the measured data is provided below

• Plot of Extreme BW RF Amplifier Gain from 10 MHz to 2 GHz (no equalization)
• Plot of Amplifier Noise Figure (no equalization)
• Plot of 1 dB Output Compression Point (Pout 1dB)
• Third Order Output Intercept Point (T.O.O.I.P) measured data
• Plot of a Three-Amplifier assembly built and tested, showing Gain from 5 KHz to 2 GHz, built as follows:
• Amp #1: No input equalization
• Amp #2: 7 dB input equalization
• Amp #3: 8 dB input equalization
• 4 dB attenuation between Amp #1 and #2, 18 dB attenuation between Amp #2 and #3
• Actual measured points of Three-Amplifier assembly Gain from 5 KHz to 2 GHz
• Plot of Amplifier Gain with resistive power divider at output (~6 dB less gain
• An example of the use of the input equalizer:
• Amplifier Gain plot without equalization (5 dB negative slope)
• Amplifier Gain plot with 6 dB positive input equalization, designed to provide about 1 dB positive slope
