Space and cost savings with CMOS 4 x 2 matrix HF switches
Equally powerful as GaAs switches, but lower in cost and more efficient
All three devices can be used in a frequency range from 250 to 2150 MHz. The isolation parameters range from 35 dBm (0.25 to 0.95 GHz) for the devices PD5715GR and PD5716GR to 42 dBm (0.25 to 2.15 GHz) for the device PD5720K. Insertion loss - depending on device type - is specified at 6.7 dBm or 6.9 dBm.
An additional 4-bit decoder was integrated in the PD5720K HF switch. By means of this decoder, four SPDT switches can be saved by 8 x 2 multi-switch circuits. The possibility to construct multi-switches on only two levels provides the user with a significant space advantage compared to a traditional design with pin diodes.
The CMOS 4 x 2 matrix HF switches PD5716GR and PD5720K, designed for an operating ambient temperature range from -40 to +850C, require 5 V supply voltage; the PD5715GR requires 3.3 V. The PD5715GR and PD5716GR devices are each offered in a Pb-free 16-pin Thermal Enhanced Thin Shrink Small Outline Package (HTSSOP); the PD5720K HF switch in a 20-pin Quad Flat No-Lead (QFN) package.
Samples and product literature for the PD5715GR, PD5716GR and PD5720K CMOS 4 x 2 matrix HF switches are available, upon request, from Gleichmann Electronics.
MSC Technologies GmbH
Founded in 1979, Gleichmann & Co. Electronics GmbH, in the same company group with MSC Vertriebs GmbH, has established itself as one of the leading pan-European distributors of electronic assemblies and components. One of the reasons for the high acceptance by customers and suppliers is the company's early focus on comparatively few, highly sophisticated products such as microcontrollers, programmable logic devices, displays and customer specific power supplies. From this, the resulting in-depth technical know-how of our sales engineers and field application engineers today enables us, if required by the customer, even implementation of complete new designs right up to the finished product. With two of its own ASIC design centers, the Gleichmann research laboratory in Austria and one of the largest and most modern programming centers in Europe, Gleichmann Electronics takes a leading role in terms of service and customer support.
