1 - 150 MHz LOW NOISE POWER AMPLIFIER WHM0010AE1
WHM0010AE amplifier is a low noise figure, high linearity, unconditional
stable, and wideband packaged amplifier module with leadless SMT design. The
amplifier offers typical 2.70 dB noise figure, 17.4 dB gain, 30 dBm P1dB, and 48 dBm

components being hermetically sealed, WHM0010AE can be custom configured to
work from –55C to +100C.
WHM0010AE is designed to meet the rugged standards of MIL-STD-202,
and MIL-STD-883.

b) Pass band Frequency Response
As shown in Figure 1, the typical gain of the WHM0010AE is 17.4 dB across 1 to 150 MHz frequency
range. The typical input and output return losses are 12 dB and 15 dB across the frequency of 1 to 150 MHz. The gain
variation is less than 0.50 dB (+/- 0.25 dB) in the frequency range from 1 to 150 MHz.
Shunting a resistor at the input can lower the amplifier gain and return losses. The resistor value of 150 Ohm
is used for gain of 15.8 dB and 75 Ohm for 14.4 dB.
Figure 2 shows the measured P1dB and IP3 of the WHM0010AE. The typical P1dB and IP3 are 30.0 dBm and
48 dBm at Vdd = +10.0V, respectively. IP3 can be improved by increase Idd to 220 mA and Vdd to 10.5 V ~ 11.0V.
Figure 3 illustrates the noise figure of WHM0010AE which is 2.70 dB at room temperature and add 0.25 dB
at +85 °C. The noise figures below 30 MHz were extrapolated based on the measured S-parameters and noise figures
beyond 30 MHz. The noise figure increases substantially with the increase of the drain DC bias voltage at the lower
frequency band (<50MHz) due to the increased thermal noise inside the power transistor junction. Thus, for low noise
applications, the amplifier should be biased at lower drain DC voltage from +6.0 V ~ +8.0V.
Figure 4 demonstrates the stability factor k of the amplifier. The amplifier is un-conditional stable since the
stability factor k is great than 1 at any frequency.
Figure 5 is the frequency response of the amplifier in Log scale.
Figure 6 demonstrates the application schematic diagram of WHM0010AE. It requires one (1) external high
Q inductor, 220 uH, for the extended low frequency operation. The inductor can be used as long as it is high Q and the
lowest self-resonance frequency is beyond 150 MHz with a rated minimum DC current of 250 mA.
The external components must be rated in the temperature range of -40 0C to 85 0C to ensure the entire
circuit working in the specified temperature range.
Figure 7 shows the mechanical outline and recommended motherboard layout of WHM0010AE. Plenty of
ground vias on the motherboard are essential for the RF grounding. The width of the 50-Ohm lines at the input and
output RF ports may be different for different property of the substrate.
5 The measured noise figure using HP8970B noise figure meter and HP346 noise source may results higher
noise figure with frequency below 30 MHz due to the limitation of the test equipment.
