RFMW Ltd. announces design and sales support for a high linearity, active bias, ultra low noise amplifier from Skyworks Solutions. The SKY67103-396LF offers mid-band noise figure of 0.6 dB for receiver applications requiring the lowest possible noise figure yet highly linear performance over a broad frequency range. Covering 500 to 4000 MHz, the SKY67103-396LF provides typical OIP3 of 34 dBm at 3.6 GHz for improved receiver selectivity and sensitivity.

Pasternack has introduced a new portfolio of solid state, high power amplifiers. These coaxial packaged RF amplifiers cover UHF, VHF, L, S and C frequency bands and are widely employed in applications such as electronic warfare, instrumentation, military communications, radar, SATCOM, telecom, data links, medical devices and many others. All of the high power amplifiers in this product family have single voltage supplies.

Designed to meet a demand among RF and microwave test engineers, this convenient-to-use and versatile amplifier covers the full 1 to 18 GHz frequency range. The rugged housing is suited to the busy laboratory environment. Built within a cast aluminium housing, 129 x 84 x 67 mm,  the amplifier delivers 35 dB gain and +20 dBm P1 output power and comes complete with a manual on-off locking toggle switch for quick application and removal of the amplified signal.

Model SBB-0132732526-KFKF-SB is a bench-top broadband power amplifier operating from 1.0 to 26.5 GHz. The amplifier provides 25 dB small signal gain and a minimum +25 dBm output power over the entire frequency range. The bench top amplifier is designed to use 100 to 240 V AC power directly from power line for laboratory use. The bench top amplifier is equipped with K connectors for RF path and measures 3.75” (W) x 4.15” (L) and 1.75” (H).

Teledyne Microwave Solutions (TMS) has extensive experience in the design and manufacture of detector log video amplifiers (DLVAs). These devices are used extensively in applications requiring an output voltage related to the power of a received RF signal. In order to cope with a wide range of input signals a log amplifier is used to provide a linear voltage output per dBm of input power.

Teledyne Microwave Solutions (TMS) offer a range of Limiting Amplifiers which are used in instantaneous frequency and phase measurement receivers. The most important performance requirement of a limiting amplifier is to minimize output power variations, and provide a constant output over a wide input dynamic range.

Gain Shape amplifiers are used in a number of applications where it's necessary to flatten the gain characteristic of the preceding or following component. This would include flattening the attenuation of a long cable run or perhaps changing the input gain response to a MPM (Microwave Power Module) or TWT (Traveling Wave Tube) to compensate for the gain variation within the tube.
