Ceramic Balun
RF Transformer
50Ω 2400 to 2500 MHz 1:4 Ratio
BLGE4-252R+
The Big Deal
• Band optimized for Bluetooth, Zigbee and low band Wi-Fi
• Tiny size, 0805
CASE STYLE: GE0805C-9
• 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 can improve a system’s electromagnetic compatibility by rejecting
unwanted common-mode noise.
Low unbalance, 0.5 dB, 2°
2W power handling
Supports a wide range of power requirements
Provides DC isolation between circuits and efficient AC transmission, eliminating the
need for external DC biasing components.
DC Isolation
Tiny size, 0805
Accommodates tight space requirements for dense PCB layouts.
