ATF-36077 2–18 GHz Ultra Low Noise Pseudomorphic HEMT Data Sheet Description Features AvagoTechnologies' ATF-36077 is an ultra-low-noise Pseudo morphic 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. The repeatable performance and consistency make it appropriate for use in Ku-band Direct Broad-cast Satellite (DBS) Television systems, C-band Television Receive Only (TVRO) LNAs, or other low noise amplifiers operating in the 2‑18 GHz frequency range. • 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 Applications 25 77 Package 20 Ga NOISE FIGURE (dB) 1.2 Pin Configuration 4 15 0.8 10 NF 0.4 0 0 4 8 ASSOCIATED GAIN (dB) • 12 GHz DBS LNB (Low Noise Block) • 4 GHz TVRO LNB (Low Noise Block) • Ultra-Sensitive Low Noise Amplifiers [1] 12 16 20 FREQUENCY (GHz) SOURCE Figure 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 (Γopt) 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 12 5.28 (0.208) .10 (0.004) TYPICAL DIMENSIONS ARE IN MILLIMETERS (INCHES).
