Device Overview

General Description

The ADM-8558 is a wideband distributed low noise amplifier capable of providing 16 dB gain and +23 dBm OIP3 from 0.005 to 20 GHz and a low 1.8 dB typical noise figure from 7 to 15 GHz. The ADM-8558 is an ideal linear signal amplifier for applications requiring low power consumption and small form-factors. ADM-8558 is available in bare die and connectorized module forms. The amplifier has excellent return losses and gain flatness.

Circuit
GNDGround -Housing or ground lug must be connected to a DC/RF ground potential with high thermal and electrical conductivity.Equivalent circuit for the Ground
RF InRF Input -This is the amplifier’s RF Input port. It is RF matched to 50 Ω and has built-in DC blocking capacitors.Equivalent circuit for the RF Input
RF OutRF Output -This is the amplifier’s RF Output port. It is RF matched to 50 Ω and has built-in DC blocking capacitors. Equivalent circuit for the RF Output
VdDrain Supply Pin -The VD pin supplies DC voltage to the drain of the amplifier IC. This pin is nominally set at +6V.Equivalent circuit for the Drain Supply Pin
VgGate Bias Pin -The VG pin provides a required positive bias which supplies the current mirror. A higher voltage results in a higher current draw through the RF Out port. This pin is nominally set at +3V.Equivalent circuit for the Gate Bias Pin

Specifications

Absolute Maximum Ratings

The Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. If these limits are exceeded, the device may become inoperable or have a reduced lifetime. Reliability limits are individual, instantaneous catastrophic limits only. Functional operation limits are indicated below. Operation of the device at multiple absolute maximum limits or for extended periods at a single limit can cause degradation and damage to the device

The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications. Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the electrical specifications. For limits, above which damage may occur, see Absolute Maximum Ratings.
