The three CMOS 4 x 2 matrix HF switches from NEC Electronics, which immediately complement Gleichmann Electronics’ product portfolio, are comparable in performance to GaAs switches, although lower in cost and – especially in multi-switch circuits – more space-saving. 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 µPD5715GR and µPD5716GR to 42 dBm (0.25 to 2.15 GHz) for the device µPD5720K. 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 µPD5720K 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 µPD5716GR and µPD5720K, designed for an operating ambient temperature range from -40 to +850C, require 5 V supply voltage; the µPD5715GR requires 3.3 V. The µPD5715GR and µPD5716GR devices are each offered in a Pb-free 16-pin Thermal Enhanced Thin Shrink Small Outline Package (HTSSOP); the µPD5720K HF switch in a 20-pin Quad Flat No-Lead (QFN) package.
Samples and product literature for the µPD5715GR, µPD5716GR and µPD5720K CMOS 4 x 2 matrix HF switches are available, upon request, from Gleichmann Electronics.
About Gleichmann & Co. Electronics GmbH
Since its foundation 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 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, graphic displays and customized battery solutions. The deep technical know-how of our sales engineers and field applications engineers enable us to implement complete new designs right up to the manufactured product to satisfy customers’ requests. Owning two ASIC design centers, a research laboratory and one of Europe’s largest, state-of-the-art programming facilities, Gleichmann & Co Electronics GmbH leads the way in custom design services.
