Analog Devices unveils IF gain block amplifiers

The ADL5535 and ADL5536 gain block amplifiers provide a high dynamic range from internally matched IF gain blocks by combining good linearity and noise figure performance, according to the company.

These versatile, multi-purpose broadband IF amplifiers cover the 20-1,000MHz frequency range and are suitable for a variety of applications that require high-performance specifications, such as in cellular, satellite, CATV, military and instrumentation equipment.

The ADL5535 and ADL5536 IF gain block amplifiers provide extremely low noise figures and very high output third-order intercept point (OIP3) specifications simultaneously across the entire 1GHz frequency range.

The ADL5535 gain block amplifier provides a flat gain of 15dB over frequency, a noise figure of 3.3dB, a P1dB of 19.1dBm and an OIP3 of 47.6dBm at 190MHz.

The ADL5536 gain block amplifier provides a flat gain of 20dB over frequency, a noise figure of 2.8dB, a P1dB of 19.8dBm and an OIP3 of 46.5dBm at 380MHz.

Both amplifiers are internally matched to 50ohm at the input and output, making these amplifiers easy to implement in a variety of applications.

Input/output AC coupling capacitors, power supply decoupling capacitors and an external inductor are required for operation.

The ADL5535 and ADL5536 IF gain block amplifiers are stable over temperature and power supply and from device to device.

They are fabricated on a GaAs HBT process and have an electrostatic-discharge rating of +/-1 kV (Class 1C).

These IF amplifiers are assembled in an MSL-1-rated SOT-89 package, making them easy to drop in to existing designs for evaluation.

The ADL5535 consumes 97mA and the ADL5536 consumes 100mA on a single 5V supply and both are fully specified for operation from -40C to +85C.

The ADL5535 and ADL5536 are available now in a three-lead SOT-89 package and are priced at USD1.75 (GBP1.07) in 1,000-unit quantities.

Complementary products include the ADL535X, ADL536X and ADL580X ranges of mixer solutions.
