Adjustable Resistor Family
A family of low power, low TC re-adjustable resistors has been designed to meet customer needs for a low cost, single element device to compensate and calibrate precision analog circuits. They are ideal for wireless, military, aerospace and satellite applications.
 
TMBS Trench Schottky Rectifier
Model V30200C is the industry’s first 200V, 30A dual high-voltage TMBS® Trench Schottky rectifier. With an extremely low VF of 0.648V typical at 15A and +125ºC, and superior switching performance, it reduces power loss and improves efficiency.
 
Reverse Polarity Terminations
These reverse polarity SMA male terminations were designed for Wi-Fi, WiMAX, and other wireless networking applications utilizing the 802.11b standard. They are RoHS compliant and have a frequency range of DC to 6 GHz with power handling of 1W.


Precision Coaxial Connectors
The company’s lines of precision coaxial connectors for flexible and semi-rigid cables are also available as solder clamp attachments. Interfaces include 1.85, 2.4, 2.92, and 3.5mm, N, SMA, and TNC. Popular cable types are HP120, HP160, HP190, LL120, LL142, LL250, and LL335. Bulkhead types are also available.

Moderate Band Reject Filter
The 5N45-4265/H1600-0/0 has a dense microwave spectrum that protects the receivers from newly deployed high-power transmitters. In such scenarios, the band reject filter is often specified as a “quick fix.” Extending the lower passband down to DC, while implementing advanced filter design techniques, can extend the upper passband to more than three times of center frequency. This enables strong rejection of moderate bandwidths.

SMB Connectors
New 75 ohm SMB connectors are available in a wide range of configurations including plugs, right-angle plugs, and PCB jacks, and are suitable for use in applications with a frequency range up to 4 GHz. This series has broadband performance with low reflection and is ideally suited for circuit miniaturization.

DDR2, DDR3 BGA Probes
The industry’s first DDR2 and DDR3 ball-grid array (BGA) probes for oscilloscopes and logic analyzers provide direct access to the balls of the DRAM with low loading and minimal impact to signal integrity.

Type N to BNC Coaxial Adapter
Model NF-BM50+ is a coaxial adapter that mates a female Type N connector to a male BNC connector. It is well suited for use as a connector saver or to interconnect equipment with dissimilar connectors. Typical insertion loss is 0.06 dB from DC to 2 GHz .

Digital Controlled Phase Shifter
Model PS-360-DC-3 Option 618 is a 6 to 18 GHz, 0 to 360º, 8 bit digitally controlled phase shifter with a switching speed of less than 50 nS, rise and fall time of less than 20 nS, insertion loss of 10 dB typical, 12 dB maximum. VSWR is 2.0:1.

Wideband Passive Mixers
Four double balanced GaAs MESFET mixers for use in test and measurement systems, military radios, commercial sensors and transceiver infrastructure, including critical functions of fixed and mobile protocols such as WiMAX and VSAT applications, are now available.
 
New Family of RF Amplifiers
The A3 family of amplifiers features an internal impedance transformer with selectable output impedance values of 12.5, 25, 50, 100, 200 and 400 ohms. An external impedance transformer is also available for applications requiring an extended range from 8 to 2000 ohms.


Connectors for LMR Series Cable
A new family of connectors for LMR type cables includes male and female Type N, 7/16, SMA and TNC connectors in straight and right angle configurations which have clamp or crimp attachment methods. Frequency coverage is from DC to 18 GHz in standard 50 ohm impedance.


 

 

 



We welcome editorial submissions to Microwave Product Digest, be they Product Features, Application Notes, White Papers, or other in-depth articles. Also, we are always looking for new perspectives for our monthly “In My opinion” column. Its topic does not necessarily need to sync with that month’s editorial focus.

Click on the link to our Editorial Calendar so you can see if there are upcoming topics you'd like to address.

Keep in mind that the deadline for such an article is approximately six weeks prior to the issue mailing date. (i.e., August 1 is the final deadline for an article to run in the September issue). Once you have something in mind, please phone Karen Hoppe, editor, at 201-569-5870 to discuss particulars... and to make certain there's room in the issue for your article.
