Measuring 2.3 x 1.7 x 0.73 mm, the BGM1033N7/BGM1032N7/BGM1034N7 receive front-end-modules (FEM) support separate or simultaneous reception of both GPS and Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) signals. The modules combine the pre-filter and LNA stages of the GNSS signal chain front-end to achieve a balance of performance improvements and space savings.
The BGM1033N7 (standard solution) meets high-performance GPS/GLONASS specifications, with 14.8-dB gain and 1.65-dB noise figure.The BGM1032N7 matches BGM1033N7 features with optimization to suppress LTE Band13 signals. The upper frequency of the LTE 13 band is 787 MHz, and the second harmonic of this frequency (i.e. 1,574 MHz) falls into the GPS band.
The BGM1034N7 is a high-gain (17.0 db) version for systems with high losses in the receive chain, such as personal navigation devices and digital still cameras, where the potential for jamming due to high power cellular signals is less critical. Common features include a current consumption of 4.0/3.1 mA, greater than 43-dBc out-of-band rejection in cellular bands, and 30-dBm input compression point in cellular bands. Housed in TSNP-7-10 packages, each of the devices also offers an 8kV IEC ESD contact discharge specification at the RF input pin. ($0.50 ea/10,000 — available now)
