1400- 3000 MHz LOW NOISE POWER AMPLIFIER WBA1530A1
WBA1530A LNA is a low noise figure, wideband,
and high linearity power amplifiers with unconditional stable
design. The amplifier offers typical noise figure of 1.0 dB, 22
dB gain, and output IP3 of 42 dBm at the frequency range from
1400 MHz to 3000 MHz.
WBA1530A is most suitable for cellular base stations,
wireless data communications, tower top amplifiers, cellular
micro-cells, last-mile wireless communication systems, MMDS,
WLL, and wireless measurement applications.

b) Passband Frequency Response
As shown in Figure 1, the typical gain of the WBA1530A is 22.0 dB across 1.40 to 3.0 GHz. The typical
input and output return losses are 20 dB and 16 dB across the frequency of 1.40 to 3.0 GHz.
Figure 2 shows the measured P1dB and IP3 of the WBA1530A. The typical P1dB and IP3 are 27.0 dBm and
42.0 dBm in the frequency range of 1.40 to 3.0 GHz, respectively.
Figure 3 illustrates the measured noise figure performance at full temperature. The noise figure is from 1.0
to 1.50 dB across the frequency range of 1.40 to 3.0 GHz at room temperature. At 85 0C, WBA1530A only has 0.35 dB
noise increases. At –40 0C, WBA1530A offers approximately 0.25 dB less noise figure than that at room temperature.
Figure 4 demonstrates the stability factor k of the amplifier. It is greater than 1.0 in full frequency band and
the amplifier is unconditional stable.
Figure 5 is the frequency response of WBA1530A in the extended frequencies. The amplifier works from
1.20 to 3.3 GHz.
Figure 6 shows the mechanical outline and recommended motherboard layout of WBA1530A. It is a
standard WP-5 connectorized housing.
