The ADL8104 is a gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), pseudomorphic high electron mobility transistor (pHEMT), low noise, wideband, high linearity amplifier that operates from 0.4 GHz to 7.5 GHz.
The ADL8104 provides a typical gain of 15 dB at 0.6 GHz to 6 GHz, a 3.5 dB typical noise figure at 0.4 GHz to 6 GHz, a 20 dBm typical output power for 1 dB compression (OP1dB) at 0.6 GHz to 6 GHz, and a typical output third-order intercept (OIP3) of 32 dBm at 0.6 GHz to 6 GHz, requiring only 150 mA from a 5 V drain supply voltage. The low noise amplifier has a high output second-order intercept (OIP2) of 52 dBm typical at 0.6 GHz to 6 GHz, making the ADL8104 suitable for military and test instrumentation applications.
The ADL8104 also features inputs and outputs that are internally matched to 50 Ω. The RFIN and RFOUT pins are internally ac-coupled and the bias inductor is also integrated, making the ADL8104 ideal for surface-mounted technology (SMT)-based, high density applications.
The ADL8104 is housed in an RoHS-compliant, 3 mm × 3 mm, 16-lead LFCSP.

Evaluation Kits (1)
The ADL8104-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 ADL8104-EVALZ are populated with 3.5 mm, female coaxial connectors, and the corresponding RF traces have a 50 Ω characteristic impedance. The ADL8104-EVALZ is populated with components suitable for use over the entire −40°C to +85°C operating temperature range of the ADL8104. 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 ADL8104-EVALZ ground path and 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 in the user guide for the test point locations).
The RF traces on the ADL8104-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 ADL8104-EVALZ represent the configuration used to characterize and qualify the device.
For full details on the ADL8104, see the ADL8104 data sheet, which must be consulted in conjunction with the user guide when using the ADL8104-EVALZ.
