The ADL8120 is an ultra-wideband low noise amplifier (LNA) that operates from 30 kHz to 20 GHz. Typical gain and noise figure are 14 dB and 1.9 dB, respectively, from 30 kHz to 14 GHz. Output power for 1 dB compression (OP1dB), output third-order intercept (OIP3), and output second-order intercept (OIP2) are 16 dBm, 29.5 dBm and 33 dBm, respectively, from 30 kHz to 14 GHz. The nominal quiescent current (IDQ), which can be adjusted, is 55 mA from a 3.3 V supply voltage (VDD). The internally matched, DC-coupled RF input and output pins require external AC coupling capacitors along with a bias inductor on RFOUT. In addition, the RF input is biased through an external inductor connected between the VBIAS pin and the RFIN pin.
The ADL8120 is fabricated on a pseudomorphic high electron mobility transistor (pHEMT) process. It is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP and is specified for operation from −55°C to +125°C.

EVAL-ADL8120
Evaluating the ADL8120 30 kHz to 20 GHz, Ultra-Wideband, Low Noise Amplifier
产品详情
The ADL8120ACPZN-EVALZ and ADL8120ACPZN-EVAL1Z are 4-layer printed circuit boards (PCBs) fabricated from 0.254 mm (10 mil) thick, Isola 370HR, copper clad, forming a nominal thickness of 1.58 mm (62 mils). ADL8120ACPZN-EVALZ was designed to support operation from 10 MHz to 20 GHz, while ADL8120ACPZN-EVAL1Z was designed to extend frequency operation down to 30 kHz. ADL8120ACPZN-EVAL1Z still operates up to 20 GHz. The RFIN and RFOUT ports on the ADL8120ACPZNEVALZ and ADL8120ACPZN-EVAL1Z are populated with 2.9 mm, female coaxial connectors, and the respective RF traces have a 50 Ω characteristic impedance. The ADL8120ACPZN-EVALZ and ADL8120ACPZN-EVAL1Z are populated with components suitable for use over the entire −55°C to +125°C operating temperature range.
To calibrate out 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 Figure 11 and Table 1 for the through calibration path performance for both the ADL8120ACPZN-EVALZ and ADL8120ACPZN-EVAL1Z.
Access the ADL8120ACPZN-EVALZ and ADL8120ACPZN-EVAL1Z ground and drain voltage through the surface-mount technology (SMT) test point connectors, GND and VDD. A supplementary test point for VRBIAS is included for simple access on the RBIAS pin (see Figure 12 and Figure 14 for the test point locations).
The RF traces on the ADL8120ACPZN-EVALZ and ADL8120ACPZN-EVAL1Z 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.
The power supply decoupling capacitors on the ADL8120ACPZNEVALZ and ADL8120ACPZN-EVAL1Z represent the configuration used to characterize and qualify the device.
For full details on the ADL8120, see the ADL8120 data sheet, which must be consulted in conjunction with this user guide when using the ADL8120ACPZN-EVALZ and ADL8120ACPZN-EVAL1Z.
