The ADL8112 is a low noise amplifier (LNA) with bypass switches that provides broadband operation from 10 MHz to 26.5 GHz. The ADL8112 provides a low noise figure of 4 dB and an output third-order intercept point (OIP3) of 22.5 dBm. The ADL8112 provides a gain of 13.5 dB that is stable over frequency, temperature, power supply, and from device to device.

The integration of an amplifier and two single-pole, four-throw (SP4T) reflective switches allow multiple paths through the device. The addition of switches also offers a high third order input intercept (IIP3) path when large input signals are present. With the integration of power supply decoupling capacitors, minimal external power supply decoupling is required.

The ADL8112 is fully specified for operation across a temperature range of −40°C to +85°C. The ADL8112 is offered in a 6 mm x 6 mm, 28-terminal land grid array (LGA) package.

    Features and Benefits

  • 4-layer, Rogers 4350B and Isola 370HR evaluation board
  • End launch, 2.92 mm RF connectors
  • Through calibration path (depopulated)
  • Product Detail

    The ADL8112-EVALZ is a 4-layer printed circuit board (PCB) fabricated from 10 mil thick, Rogers 4350B and Isola 370HR, copper clad, forming a nominal thickness of 62 mils. The RFIN and RFOUT ports on the ADL8112-EVALZ are populated with 2.92 mm, female coaxial connectors, and the corresponding RF traces have a 50 Ω characteristic impedance. The ADL8112-EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the ADL8112. To calibrate board trace losses, two through calibration paths are provided. Install RF connectors in the J5, J6, J11, and J12 positions to use the through calibration paths. Refer to Table 1 and Figure 3, in the user guide, for the through calibration RF path performance.

    Access the ADL8112-EVALZ power supply and digital control pins through the surface-mount technology (SMT) test point connectors, VDD_PA, GND, VDD_SW, VSS_SW, VA, and VB.

    The RF traces on the ADL8112-EVALZ are 50 Ω, grounded, coplanar waveguides. The package ground leads and the exposed pad connect directly to the ground plane. Multiple vias connect the top and bottom ground planes with particular focus on the area directly beneath the ground paddle to provide adequate electrical conduction and thermal conduction to the ADL8112-EVALZ.

    Figure 4, in the user guide, shows the ADL8112-EVALZ schematic and configuration used to characterize and qualify the device.

    For full details on the ADL8112, see the ADL8112 data sheet, which must be consulted in conjunction with the user guide when using the ADL8112-EVALZ.
