The Big Deal

• Band optimized for Bluetooth, Zigbee and low band Wi-Fi

• Tiny size, 0805

• Low insertion loss, 0.5 dB

• Low unbalance, 0.4 dB, 4°

• Low cost

Product Overview

Mini-Circuits BLGE4-252R+ is a miniature ceramic RF balun transformer with an impedance ratio (second-

ary/primary) of 1:4. This model covers the 2400 to 2500 MHz frequency band and has been performance

optimized for use in Bluetooth, Zigbee and low band Wi-Fi applications. This model provides low insertion

loss, low amplitude unbalance, and RF input power handling up to 2W. Fabricated using LTCC technology,

it comes housed in a tiny package (0.08 x 0.05 x 0.04”) and is suitable for high-volume production.

Key Features

Feature

Advantages

Low insertion loss, 0.5 dB

Enables excellent signal power transmission from input to output.

Low unbalance, 0.5 dB, 2°

Low unbalance can improve a system’s electromagnetic compatibility by rejecting

unwanted common-mode noise.

2W power handling

Supports a wide range of power requirements

DC Isolation

Provides DC isolation between circuits and efficient AC transmission, eliminating the

need for external DC biasing components.

Tiny size, 0805

Accommodates tight space requirements for dense PCB layouts.
