1 5MHz 3.GHz Gallium Nitride MMIC Power Amplifier AM342WN- AM342WN-SN-R January 219 Rev 1 DESCRIPTION AMCOM s AM342WN- is an ultra-broadband GaN MMIC power amplifier. It has 23dB gain, and >42dBm output power over the.5 to 2GHz band. This MMIC is matched to 5 Ohms at the input but un-matched at the output above 2GHz. The chip is also available in a package (AM342WN-SN-R). Chip and package can give good power up to 5GHz over limited bandwidth by matching the output port externally. The chip and package are RHoS compliant. FEATURES Ultrawide bandwidth from 5MHz to 3GHz Saturated output pulse power P5dB > 42dBm Small signal gain, 23dB Input matched to 5 Ohms APPLICATIONS Software Radio, ECM Instrumentation Gain block CHIP TYPICAL PERFORMANCE (AM342WN-) * A) Bias Conditions**: V dd1 = V dd2 = +28V, I ddq1 = 4mA, I ddq2 = 5mA Parameters Minimum Typical ** Maximum Frequency.1 2.5GHz.5 3GHz Small Signal Gain 2dB 23dB 26dB Gain Ripple ± 1dB ± 2dB 35dBm 37dBm 1.GHz 34dBm 36dBm 2.GHz 34dBm 38dBm 4dBm 1.GHz 38dBm 4dBm 2.GHz 4dBm P5dB 35% P5dB 1.GHz 32% P5dB 2.GHz 27% Noise Figure (.5 4GHz) < 18dB IP3 (.1 1.1GHz) 46dBm Input Return Loss 15dB 18dB Output Return Loss 5dB Thermal Resistance.95 C/W info@amcomusa.com Tel.

Inductance of choke should be large enough to have high impedance at lowest frequency of operation (1nH is adequate). 2- Input RF power should not exceed.5w 3- Recommended current biases are 4mA and 5mA for the first stage and second stage respectively. Gate biases of -2V are for reference only. Vgs1& Vgs2 could be adjusted to vary the currents going thru the first stage (Vdd1 pin) and the second stage (Vdd2 pin) respectively. Vgg2 to be applied thru 1 Ohms should be equal to Vdd2. 4- Do not apply Vdd1& Vdd2 without proper negative voltages on Vgs1& Vgs2. Otherwise MMIC would fail due to excess heat. 5- Chip is only matched up to 2GHz. For applications above 2GHz output matching improves performance up to 5GHz. Make sure power dissipation is less than 5W. Since the MMIC is not matched above 2.5GHz do not operate above 2.5GHz at power saturation at > +45V to avoid failure. info@amcomusa.com Tel. (31) Fax.
