2-18 GHz Ultra Low Noise Pseudomorphic HEMT Technical Data ATF-36077 Features Description * PHEMT Technology * Ultra-Low Noise Figure: 0.5 dB Typical at 12 GHz 0.3 dB Typical at 4 GHz * High Associated Gain: 12 dB Typical at 12 GHz 17 dB Typical at 4 GHz * Low Parasitic Ceramic Microstrip Package * Tape-and-Reel Packing Option Available Hewlett-Packard's ATF-36077 is an ultra-low-noise Pseudomorphic High Electron Mobility Transistor (PHEMT), packaged in a low parasitic, surface-mountable ceramic package. Properly matched, this transistor will provide typical 12 GHz noise figures of 0.5 dB, or typical 4 GHz noise figures of 0.3 dB. Additionally, the ATF-36077 has very low noise resistance, reducing the sensitivity of noise performance to variations in input impedance match, making the design of broadband low noise amplifiers much easier. The premium sensitivity of the ATF-36077 makes this device the ideal choice for use in the first stage of extremely low noise cascades. 25 Note: 1.

The Fmin values at 2,4, and 6 GHz have been adjusted to reflect expected circuit losses that will be encountered when matching to the optimum reflection coefficient (opt) at these frequencies. The theoretical Fmin values for these frequencies are: 0.10 dB at 2 GHz, 0.20 dB at 4 GHz, and 0.29 dB at 6 GHz. Noise parameters are derived from associated s parameters, packaged device measurements at 12 GHz, and die level measurements from 6 to 18 GHz. 77 Package Dimensions Part Number Ordering Information 1.02 (0.040) SOURCE 4 1 GATE SOURCE 360 .51 (0.020) Part Number No. of Devices Container ATF-36077-TRl[2] 1000 7" Reel ATF-36077-STR 10 strip Note: 2.
