20 MHz to 6 GHz RF/IF Gain Block, Fixed Gain of 20 dB
The ADL5542 is a broadband 20 dB linear amplifier that operates at frequencies up to 6 GHz. The device can be used in a wide variety of CATV, cellular, and instrumentation equipment.
The ADL5542 provides a gain of 20 dB that is stable over frequency, temperature, power supply, and from device to device. The device is internally matched to 50 Ω with an input return loss of 10 dB or better, up to 6 GHz. Only input/output ac coupling capacitors, power supply decoupling capacitors, and an external inductor are required for operation.
The ADL5542 is fabricated on an InGaP HBT process and has an ESD rating of 1 kV (Class 1C). The device is packaged in a 3 mm × 3 mm LFCSP that uses an exposed paddle for excellent thermal impedance.
The ADL5542 consumes 93 mA on a single 5 V supply and is fully specified for operation from −40°C to +85°C.
A fully populated RoHS-compliant evaluation board is available.
The ADL5541 is a companion part that offers a gain of 15 dB in a pin-compatible package.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
ADL5542-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation it requires a single 5 V/100 mA power supply. The 5 V power supply should be connected to the test loops labeled VCC and GND. Alternatively, the power supply connections may be made via the two pin header, W-1. The RF input is applied to the SMA connector labeled RFIN. The RF output is available at the SMA connector labeled RFOUT.
