RCT0050 Wide-band Amplifier (0.5 - 18.0 GHz), by R. A. Wood Associates

R. A. Wood Associates has designed and built a new wide-band amplifier, using surface mount technology. The amplifier can be utilized across the frequency band: 0.5 - 18.0 GHz. This is an ideal amplifier for Electronic Warfare (EW) applications in high dynamic range locations. It had good wideband flatness, high dynamic range, and very good noise figure for its high 1dB compression point. Performance in narrower bands is even better, as shown in the tables and plots. We are keeping these built ahead to improve the delivery time.

If you are interested in pricing and delivery, please contact us.

The wide-band performance of the RCT0050 WB Amplifier can be seen in the plots below. The plots display typical measured data for various parameters such as gain (S21), output 1dB compression point (P1dB), input return loss (S11) and output return loss (S22). Typical current draw for the amplifiers is approximately 200mA. These amplifiers can be built rather quickly with surface mount assembly.

RCT0050 Amplifier Typical Data

The table below shows typical data for the RCT0050 Wide-band Amplifier. The input and output return loss (S11 and S22) values are representative of the maximum values over the various frequency bands. The P1dB value is representative of the minimum value over the various frequency ranges, and is associated with the output. The peak to peak (P-P) value is the difference, in decibels, between the positive and negative peak of the measured gain value. "NF" refers to the noise figure maximum for each respective band.

The table below contains links to plots, and is meant to accompany the table above. Over the various bands of the table above, our amplifier's typical performance can be seen if you click on the respective link.
The input and output return loss (S11 and S22) values can be seen across the various bands listed in this table. The P1dB value can be seen plotted across the various bands (remember, it is associated with the output). The peak to peak (P-P) value can also be seen to the right of the plots once clicked on. P-P variation from the best fit line can be seen once gain plots are clicked on.
