Device Overview

General Description

The ADM-8344PSM is a wideband distributed low noise amplifier capable of providing 19 dB gain and +29 dBm OIP3 from DC to 18 GHz and a low 1.7 dB typical noise figure from 4 to 14 GHz. The ADM-8344PSM is an ideal linear signal amplifier for applications requiring low power consumption and small form-factors. ADM-8344 is available A 4mm QFN and can be supplied from a single positive bias. The amplifier has excellent return losses and noise figure performance.

Port Functions

PortFunctionDescriptionDC Equivalent
Circuit
PaddleGround The package ground paddle must be connected to a DC/RF ground potential with high thermal and electrical conductivity.Equivalent circuit for the Ground
Pin 11ACG This pin provides AC ground for the internal circuit. This pin should be connected to ground through a bypass capacitor as shown in the application schematic. This pin should not be connected directly to GND.-
Pin 16RF Out / Vd Pin 16 is the RF output and primary DC power supply of the amplifier. This pin is internally RF matched to 50 ohms and requires an external bias-tee connected to a positive DC supply voltage. The voltage, Vd, at this pin should be set to 5V for normal operation.Equivalent circuit for the RF Out / Vd
Pin 22ACG This pin provides AC ground for the internal circuit. This pin should be connected to ground through a bypass capacitor as shown in the application schematic. This pin should not be connected directly to GND.-
Pin 4RF Input Pin 4 is the amplifier's RF input pin. This pin is internally RF matched to 50 Ohms and requires an external DC blocking capacitor.Equivalent circuit for the RF Input
Pin 9Vb Pin 9 provides positive DC bias voltage to the amplifier. This pin is internally connected to a current mirror controlling amplifier drain current. A higher voltage on this pin results in higher current draw through the Vd / RF out pin. The voltage at this pin should be set to 5V for normal operation.Equivalent circuit for the Vb
Pins 1-3,5-8,10,12-15,17-21,23,24Non-connect (NC) These pins are not connected internally. They should be grounded for best performance. Datasheet performance is measured with these pins grounded.-

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.
