Product Overview:
YSF-122+ is an advanced amplifier module in a Mini-Circuits System In Package
™ . This module is fully
matched to 50Ω in/out impedance and has built-in Input & Output DC block capacitors. It is enclosed in a
5 x 6 mm MCLP plastic package. The YSF-122+ uses E-PHEMT technology enabling it to work with a
single positive supply voltage.
Key Features
Feature
Advantages
The YSF-122+ provides industry leading gain flatness over the full cellular communi-
cations L band (800-1200 MHz) making this ideal for use in applications where gain-
flatness and repeatability are critical performance requirements.
Superior Gain Flatness 0.2dꢀ
The YSF-122+ is a two-stage design with internal feedback and bias to provide flat
20 dꢀ nominal gain, supporting applications where a single gain block must overcome
large system losses such as long cable runs and lossy components.
High Gain
The YSF-122+ provides a strong combination of performance parameters including
high gain (20 dꢀ), high IP3 (+37 dꢀm) and P1dꢀ (+20 dꢀm) and low noise figures (3.4
dꢀ) that are difficult to achieve in a single stage design and available only in the YSF
amplifier series.
Strong Combination of Performance
The YSF-122+ includes all support circuits including: Matching, ꢀias and DC ꢀlock-
ing, all integrated into a single 5x6mm package making the total footprint equal to or
smaller than most solutions.
Integrated Matching, DC ꢀlocking and
ꢀias in Small Package
The YSF-122+ includes integrated input and output matching and bias circuits to
make this amplifier a simple, complete drop-in solution. The matching circuits provide
excellent output return loss (17dꢀ), and are designed to give optimal P1dꢀ and IP3
performance in a 50Ω environment.
Excellent Return Loss
High Reverse Isolation
With 30 dꢀ of reverse isolation – the YSF-122+ is an ideal gain block for use in inte-
grated systems to minimize VSWR interactions resulting from cascading highly reflec-
tive components such as sharp filters.
