An RF (Radio Frequency) & MW (Microwave) Power Amplifier (PA) stage is usually the final active block of any electronic system that is transmitting RF Power. Whether the amplifier is designed as a small MMIC used to transmit lower power (such as in cellular hand-sets and other portable applications) or a large rack-mounted PA used in high power RF systems (such as DVB-T Broadcast, Cellular/PCS Wireless Infrastructure and Military RADAR), it provides essentially the same function. Relatively low power RF signals are amplified to produce a more powerful signal in order to be transmitted over greater distance.
Most Power Amplifiers are designed for a specific application (e.g. HDTV, GSM, Radar, Point-to-Point Microwave, LTE) employing a specific signal type, modulation scheme, and a set of specifications. It is important to match the attributes of the amplifier product to the needs of the application. The specific attributes which are important in selecting the right RF & MW Power Amplifier include “Technology” (GaN, GaAs, InGaP, LDMOS), Frequency Range, Gain (dB), Gain Flatness (dB), Supply Voltage (VDC), P1dB (dBm), and Package Type.
From the relatively low power MMIC (typically less than 2 watts output power), to the medium power RF stage (either a connectorized hybrid design or a thermally-enhanced surface mount integrated circuit package), to the highest power pallets, enclosed modules and rack-mount units, Richardson RFPD / Arrow RF & Power offers a full range of RF & MW Power Amplifiers. Our main suppliers include ANADIGICS, Freescale Semiconductor™, M/A-COM Technology Solutions, Microsemi, TriQuint Semiconductor, and United Monolithic Semiconductors. Please note that we also supply the accompanying Thermal Management Systems designed to help cool RF & MW power amplifiers.
The parametric search filter allows the user to quickly find the parts they need by filtering the results in real-time.
Additionally, some attributes allow for the conversion of their base type to different types. For example, the attribute group for minimum frequency is shown in MHz. The values can be converted to be shown in KHz or GHz by selecting the conversion type from the ‘Select Conversion’ drop down list.
Any Attribute that does not interest the user can be hidden by clicking on the ‘X” in the upper-right corner of the attribute. To show any hidden attributes, simply click the ‘Unhide Attributes’ button in the bottom of the parametric search filter.
If you are experiencing performance issues, please use a newer browser such as Chrome or Firefox, or disable the ability of the filter to perform dynamic updates by deselecting the checkbox titled ‘Allow Filters to Dynamically Update Parametric Search Attributes’.
