ADL8105是一款砷化镓(GaAs)、单芯片微波集成电路(MMIC)、假晶高电子迁移率晶体管(pHEMT)低噪声宽带放大器，工作频率范围为5 GHz至20 GHz。

在12 GHz至17 GHz范围内，ADL8105提供27 dB典型增益、1.8 dB典型噪声系数和30.5 dBm典型输出三阶交调截点(OIP3)以及高达20.5 dBm的饱和输出功率(PSAT)，采用5 V电源电压时功耗仅为90 mA。可通过牺牲OIP3和输出功率(POUT)来降低功耗。ADL8105还具有内部匹配50 Ω的输入和输出。RFIN和RFOUT引脚均内部交流耦合，同时集成了偏置电感，使其非常适合基于表贴技术(SMT)的高容量微波无线电应用。

ADL8105采用符合RoHS标准的2 mm × 2 mm 8引脚LFCSP封装。

EVAL-ADL8105：Evaluating the ADL8105 Wideband, High Linearity, Low Noise Amplifier, 5 GHz to 20 GHz

The ADL8105-EVALZ consists of 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 ADL8105-EVALZ are populated with 2.9 mm, female coaxial connectors, and the corresponding RF traces have a 50 Ω characteristic impedance. The ADL8105-EVALZ is populated with components suitable for use over the entire ?40°C to +85°C operating temperature range of the ADL8105. To calibrate board trace losses, a through calibration path is provided between the J1 and J2 connectors. J1 and J2 must be populated with RF connectors to use the through calibration path. Refer to Table 1 and Figure 3 in the user guide for the through calibration path performance.

Access the ADL8105-EVALZ ground path and the VDD pin through the surface-mount technology (SMT) test point connectors, GND and VDD. A supplementary test point for VBIAS is included for simple access on the RBIAS pin (see Figure 5 for the test point locations).

The RF traces on the ADL8105-EVALZ are 50 Ω, grounded, coplanar waveguide. 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 heat sink.

The power supply decoupling capacitors on the ADL8105-EVALZ represent the configuration used to characterize and qualify the device.

For full details on the ADL8105, see the ADL8105 data sheet, which must be consulted in conjunction with the user guide when using the ADL8105-EVALZ.
