R. A. Wood Associates QuickNews

We've developed a new Ultra-Wideband Microwave Amplifier, the RCT0050, covering the frequency band of 0.5 to 18 GHz. This amplifier is built using surface mount technology, resulting in a lower production cost than traditional MIC amplifiers, with faster delivery times. Typical amplifier characteristics are:

• ~19 dB Average Gain
• <3.0 dB P-P Flatness
• 22 dBm Average Pout 1 dB
• Noise Figure ranging from <2 dB to 5.0 dB.
• ~200 mA Current Draw from +12 V

This is a great overall amplifier for low noise, high dynamic range, wideband EW applications, or narrowband applications. More information is available from this link. Let us know if you are interested in this product!
