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
