The RoHS-compliant gain block has noise figure of less than 2 dB and composite-second-order (CSO) performance of better than −75 dBc. The composite-triple-beat (CTB) performance is −77 dB. The gain block is supplied in a SOIC-8 package and provides +24 dBm output power at 1-dB compression (P1dB). The gain block, which is suitable for use with optical receivers, laser drivers, and balanced antenna systems, draws 277 mA at +4.5 to +5.5 V dc.
Oscilloscopes Add Waveform Generator Option
R&S RTO2000 and R&S RTE series high-speed oscilloscopes are now available with a 100-MHz-bandwidth arbitrary waveform generator and pattern generator option that provides two analog signal channels and eight digital signal channels that are operated by an oscilloscope’s controls. The oscilloscopes are available with two or four channels and analysis bandwidths from 600 MHz to 6 GHz. The integrated test source, with data rates to 40 MSample/s, simplifies measurement setups by eliminating the need for an external signal generator.
GaN Amp Assembly Powers Four Bands
The SSPA 0.1-3.5-500 is a GaN-based power amplifier assembly that operates across VHF, UHF, L-band, and S-band frequencies. Suitable for communications or electronic-warfare (EW) applications, it provides separate TNC female input connectors for each of the four bands and combines all four into a single output connector.
The amplifier assembly measures 6.0 × 9.0 × 3.0 in. and incorporates reverse polarity protection, open- and short-circuit protection,and over- and under-voltage protection. It provides +53 dBm output power with at last 25-dB gain at VHF; +50 dBm output power with at least 21.8-dB gain at UHF; +49 dBm output power with at least 24.2-dB gain at L-band; and +49-dBm output power with at least 21.5-dB gain at S-band. The bands can be switched on and off in 100 μs or less. The amplifier assembly, with 2.0:1 input and output VSWR, is designed for operating temperatures from −40 to +85ºC.
SMPM Cable Assemblies Extend DC to 20 GHz
SMPM coaxial cable assemblies are available in fixed lengths from 3 to 48 in. (10 to 200 cm) for applications to 20 GHz. The cable assemblies are suitable for high-reliability applications, including in military and aerospace systems. The 50-Ω cable assemblies feature low-loss SMPM plug connectors that function with both radial and axial misalignments, enabling them to perform well when exposed to high levels of shock and vibration.
Attenuator is Continuously Variable from 2 to 4 GHz
The P4804-10 continuously variable provides a 10-dB attenuation range from 2 to 4 GHz. The panel-mount attenuator is ideal for applications where front-panel adjustments must be made. It achieves 0.1-dB or better resettability and handles 5 W average power and peaks as high as 5 kW. The maximum insertion loss is just 0.5 dB and maximum VSWR is 1.80:1. The attenuator is supplied with SMA female connectors and is designed for operating temperatures from −55 to +85ºC.
Manually Tuned Filter Screens 4 to 6 GHz
Model 5CTB-4000/6000-5-N/N is a manually controlled tunable bandpass filter covering 4,000 to 6,000 MHz. Based on a multiple-section Chebyshev filter architecture, the filter provides a passband with 3-dB bandwidth that is within 5% of the tuned center frequency. The filter exhibits low passband insertion loss of 1 dB or less, and delivers 50-dB out-of-band rejection for frequencies that are 3.5 times lower or higher than the tuned center frequency. The tuned dial accuracy is ±1%. Although not specified for maximum input power, lower-frequency models in the series are rated for input power levels as high as 50 W CW.
Combiner/Divider Spans 3 to 5 GHz
The 802-2-4.000-M01 power divider/combiner maintains 0.3 dB maximum insertion loss above the theoretical 3.01-dB division loss from 3 to 5 GHz with an average power rating of 20 W. The 50-Ω combiner/divider exhibits input VSWR of 1.30:1 and output VSWR of 1.25:1. It provides at least 20 dB isolation between ports, with amplitude balance within 0.2 dB and phase balance within 4 deg. The RoHS-compliant component is equipped with passivated stainless-steel female SMA connectors and is usable at temperatures from −55 to +85ºC.
Programmable Attenuator Controls 0 to 60 dB to 13 GHz
The RUDAT-13G-60 programmable attenuator features an attenuation range of 0 to 60 dB, adjustable in 0.5-dB steps from 10 MHz to 13 GHz. It achieves typical attenuation accuracy of ±0.5 dB. The RoHS-compliant, single-channel attenuator has high linearity, with typical input third-order intercept point (IP3) of +41 dBm through 13 GHz. It includes USB, RS-232, and SPI (via a D-sub connector) interfaces for easy control from a user’s PC, with software support available by means of free download from the Mini-Circuits website. The 50-Ω programmable attenuator measures just 2.0 × 3.0 × 0.6 in. and is well suited for use in automated test systems, radar testing, and receiver sensitivity testing.
