| 2-18 GHz Ultra Low Noise Pseudomorphic HEMT Technical Data ATF-36077 Features * 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 Description 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. ASSOCIATED GAIN (dB) 77 Package Pin Configuration 4 SOURCE Applications * 12 GHz DBS LNB (Low Noise Block) * 4 GHz TVRO LNB (Low Noise Block) * Ultra-Sensitive Low Noise Amplifiers Note: 1. See Noise Parameter Table. 1 GATE 360 3 DRAIN 2 SOURCE 25 20 Ga 1.2 NOISE FIGURE (dB) 15 0.8 NF[1] 10 The repeatable performance and consistency make it appropriate for use in Ku-band Direct Broadcast Satellite (DBS) Television systems, C-band Television Receive Only (TVRO) LNAs, or other low noise amplifiers operating in the 2-18 GHz frequency range. This GaAs PHEMT device has a nominal 0.2 micron gate length with a total gate periphery (width) of 200 microns. Proven gold based metalization systems and nitride passivation assure rugged, reliable devices. 5965-8726E 0.4 0 0 4 8 12 16 20 FREQUENCY (GHz) Figure 1.

Maximum Available Gain, Maximum Stable Gain and Insertion Power Gain vs. Frequency. VDS = 1.5 V, ID = 10 mA. 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 1.02 (0.040) SOURCE 4 .51 (0.020) 1 GATE Part Number Ordering Information Part Number ATF-36077-TRl[2] ATF-36077-STR No. of Devices 1000 10 Container 7" Reel strip 3 DRAIN Note: 2.
