1M05nxp.jpg

Low Noise Amplifiers
As the industry’s first GPS LNAs to dynamically suppress strong cellular, Bluetooth and WLAN transmit signals, the NXP BGU700x family offers the best reception for weak GPS signals, delivering an improvement of 10 dB or better IP3 under -40 to -20 dBm jamming conditions, while the noise figure remains below 1 dB. Requiring only two external components, the BGU700x LNAs save up to 50 percent in PCB size and 10 percent in component cost. The NXP BGU700x/BGU8007 series use adaptive biasing to immediately detect any output power from jammers, and compensate by temporarily increasing the current. As a result, optimal GPS signal reception is maintained for as long as possible. Each device in the BGU700x/BGU8007 series requires only one input matching inductor and one supply decoupling capacitor to complete the design. This creates a very compact design and lowers the bill of materials. For example, the BGU7005 is in a 1.45 × 1 mm package with an application area of only 4.53 × 4.53 mm.

Material

Heatsink
Designed for applications requiring high power densities and where forced air cooling is present, Ohmite has released a larger version of its MV/MA heatsink, which provides even more heat dissipation. The longer, more efficient fin extrusions on the new version give nearly twice the thermal performance as their smaller MV/MA 102 product. The MV/MA 302 heatsink is 2.2" × 1.71" and uses the same installation mechanism, which provides two internal spring clips for mounting up to four TO-247 or TO-264 devices.  The spring clips eliminate the need for mounting holes and screws, are resilient and provide the same amount of force after repeated use.
