PRODUCT OVERVIEW
Mini-Circuits PHA-22+ is a dual matched wideband amplifier fabricated using advanced E-PHEMT technology, offering high
dynamic range (High IP3 and Low NF) for use in 50 and 75 ohm applications. Exceptionally high IP2 has been demonstrated in
wideband 50 and 75 ohm amplifiers evaluation boards. Combining this with low noise figure to enable it for use in exceptionally
high dynamic range amplifiers.
KEY FEATURES
Feature
Advantages
Broadband
Covers Cable TV band and communication bands such as Cellular, Cable TV, PCS, WiMAX etc.
Matched pair for use in exceptionally
high IP2 amplifiers
Typical gain match of 0.2 dB and phase match of 1.6 deg. enables it to be used in push-pull amplifiers. Outstanding IP2.
High IP3, up to 43 dBm
Ideal for suppressing unwanted intermods in the presence of multi carriers, which is common in present day communication systems.
Low Noise Figure: 1.8 dB typical
Compare this to the competitors, which is in the range of 4-6 dB. Mini-Circuits amplifier improves the dynamic range.
High P1dB: 22 dBm
High P1dB enables the amplifier to operate in linear region in the presence of strong interfering signals.
a. Suitability for model replacement within a particular system must be determined by and is solely the responsibility of the customer based on, among other things, electrical performance
criteria, stimulus conditions, application, compatibility with other components and environmental conditions and stresses.
b. The WJ part number is used for identification and comparison purposes only.
