1400 to 1700 MHz

CASE STYLE: CA531

The Big Deal

• Good Directivity, 17 dB typ.

• Excellent Power Handling, 4W

• Small Size, 3.1 x 3.0 x 1.6mm

Product Overview

Mini-Circuits D19GA+ is a MMIC Directional Coupler designed for applications from 1400 to 1700 MHz.

This model provides excellent power handling up to 4W in a tiny device package (3.1 x 3.0 x 1.6 mm). A

built-in 50Ω termination on the isolated port simplifies circuit design and reduces component count. Manu-

factured using Silicon IPD technology, this model provides a high level of ESD protection and excellent

reliability.

Key Features

Feature

Advantages

Low insertion loss; 0.3 dB including

coupling loss

Can be used for sampling power amplifier output with minimal loss.

Excellent power handling; 4W (IN-OUT)

Ideal for sampling transmitter output power.

Good directivity, 17 dB typ.

Good directivity minimizes coupling of reverse power and enables accurate sampling of

the thru-signal.

High operating temperature

-40 to 105°C

Operation up to 105°C allows the Coupler to be used near power amplifiers with minimal

change in performance.

Excellent ESD

Class 1B (500 to <1000V)-HBM

Class M3 (200 to <400V)-MM

Rugged ESD design prevents ESD related failures.
