ADL5611

30 MHz to 6 GHz RF/IF Gain Block
Manufactured by:

Product Details

The ADL5611 is a single-ended RF/IF gain block amplifier that provides broadband operation from 30 MHz to 6 GHz. The ADL5611 provides a low noise figure of 2.1 dB with a very high OIP3 of 40.0 dBm simultaneously, which delivers a high dynamic range.

The ADL5611 provides a gain of 22.2 dB that is stable over frequency, temperature, and power supply, and from device to device. The amplifier is offered in the industry-standard SOT-89 package and is internally matched to 50 Ω at the input and output, making the ADL5611 easy to implement in a wide variety of applications. The only external parts required are the input and output ac coupling capacitors, power supply decoupling capacitors, and bias inductor.

The ADL5611 has a high ESD rating of ±1.5 kV (Class 1C) and is fully specified for operation across a wide temperature range of −40°C to +105°C.

A fully populated RoHS-compliant evaluation board is available.

Product Details

ADL5611-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation it requires a single 5 V/200 mA power supply. The 5 V power supply should be connected to the test loops  labeled VCC and GND. The RF input is applied to the SMA connector labeled RFIN. The RF output is available at the SMA connector labeled RFOUT.

ADL5611 is RF amplifier feature excellent noise figure specifications over a wide frequency range (actual -5.6 dB at 6 GHz) and are internally matched to 50 Ω at the input and output. This requires a minimal number of external components. Performed in a convenient package (SOT-89). It is very good RF amplifier.

LNA AD5611
i use RF amplifier AD5611 as LNA before mixer, to compensate filter attenuation, and i can say this make a very good job with a gain of 22.2 dB that is stable over frequency and temperature ! Because of 50 Ohm impedance, this is PERFECT for RF applications, where impedance match is so important

about ADL5611
The ADL5611 is a great monolitic RF amplifier, with a gain of 22.2 dB and is very stable over frequency or temperature, without auto oscillations. Is matched perfectly to 50 Ω at the input and output , perfect for any RF projects ! This RF amplifier, help me very much for wide band with his gain, that compensate loss of long cable from antenna, and match PERFECT for my project ! Thank you Analog Devices ! regards, alexander
