Multiband Modular RF Receivers downconvert antenna signals.

Press Release Summary:

Multiband Modular RF Receivers downconvert antenna signals.

Jan 10, 2013 - Used stand-alone or integrated on 3U VPX or larger carrier modules, Model 8111 series accepts 800 MHz to 3 GHz RF signals and downconverts them to 225 MHz IF signal suited for A/D conversion by signal acquisition modules. Internal frequency-synthesized local oscillator can be locked to external 10 MHz reference signal for precise tuning accuracy, or on-board 10 MHz OCXO can serve as frequency reference. Each tuner is provisioned with one of 7 different 400 MHz bandwidth preselector filters.

Pentek Introduces New Line of Multiband, Modular RF Downconverters

Press release date: Jan 08, 2013

• Ideal for amplifying and downconverting antenna signals
• Easy integration into RF systems
• High dynamic range and low noise
• Accepts RF signals from 800 MHz to 3 GHz
• 225 MHz IF output with 80 MHz output bandwidth
• Seven pre-select filter ranges

WASHINGTON, D.C.–Pentek, Inc., today announced a new line of multiband, modular RF slot receivers: the Model 8111 series accepts RF signals over the range of 800 MHz to 3 GHz, downconverting them to a 225 MHz IF signal suitable for A/D conversion by any of several Pentek signal acquisition modules.

"The Model 8111 complements Pentek's software radio offerings by capturing the RF signal right from the antenna and delivering the IF output straight into Pentek A/D boards," said Paul Mesibov, chief technology officer and co-founder of Pentek. "Some customers do not need an RF receiver that tunes across a wide spectrum, but rather just a slice or 'slot'. Our new slot receivers not only deliver the required high-performance downconversion, they also offer a lower-power solution that is smaller, lighter and less expensive, about one fifth the cost of a wide range receiver," he added.

Tuning Accuracy
The internal frequency-synthesized local oscillator can be locked to an external 10 MHz reference signal for precise tuning accuracy. Alternatively, an on-board, low noise 10 MHz oven-controlled oscillator (OCXO) can be used as the frequency reference. For custom applications, an external local oscillator signal can also be supplied.

Preselector Options
Each tuner is provisioned with one of seven different 400 MHz bandwidth preselector filters covering the RF input range from 800 MHz to 3 GHz. The preselect filters overlap slightly to ensure that there are no gaps in RF spectrum coverage.

Wide IF Output
An 80 MHz wide IF output is provided at 225 MHz, suitable for A/D conversion using Pentek's high-performance signal acquisition products.

Programmable Input Level
Low noise figure amplifiers and two programmable attenuators accommodate RF input signals from -60 dBm to -20 dBm, and deliver a nominal IF output level of 0 dBm. Higher-level signals can be attenuated prior to input.

Easy Set Up and Connectivity
The Model 8111 modules are designed to be used as stand-alone or integrated on carrier modules in a 3U VPX size or larger. The module features a MicroUSB port for programming, a Micro-D connector for power and SMA connectors for signals, all in a high-performance, shielded enclosure. Future modules from Pentek will be available on a range of popular open standard form factors.

Pricing and Availability
The Model 8111 starts at less than $5,000. Delivery is 10-12 weeks ARO. Pricing varies depending on the pre-select filter option.
