MMIC RF functional blocks from Guerrilla, in distribution
Recently announced is a failsafe SPDT switch for cellular boosters, cellular infrastructure and
L-band Satellite Communications – the GRF6011. This linear, ultra-low loss switch has been designed with failsafe characteristics when all voltage inputs are removed. In switching mode, the device delivers IP1dB levels greater than 1 Watt along with >49 dBm IIP3 levels for both RF paths. When powered down (Failsafe Mode), RFC (switch common) to RF1 (n/o swich terminal) defaults to a high insertion loss while RFC to RF2 (n/c path) defaults to a low insertion loss state that retains high linearity.
GRF2013 is a high performance broadband gain block featuring high linearity with low noise designed for small cell, wireless infrastructure and other high performance applications. It exhibits outstanding broadband noise factor, linearity and return losses over 0.7 to 3.8 GHz with a single match. Optimizing the bias inductor and coupling caps for lower frequency operation will yield good performance down to 50 MHz. The addition of simple external matching optimises linearity and gain performance up to 8 GHz.
As a first stage LNA, linear driver or cascaded gain block the GRF4003 is a multi-purpose component offering high levels of reuse across varied designs and applications. Designed for small cell, wireless infrastructure and other applications, the GRF4003 maximises broadband NF, linearity and return losses over 100 to 3800 MHz with a single match. The GRF5110 is a high linearity PA/Linear Driver with low noise figure (NF). It delivers a P1dB of 28.8 dBm, plus excellent IP3 and NF over a range of frequencies from 1500 to 3800 MHz with fractional bandwidths >20%.
For ultra-low noise applications Guerrilla has the GRF207X family of pin compatible, ultra-low noise devices. With four amplifiers covering the frequency bands from 400 MHz to 6.0 GHz the GRF2070/2071/2072 and 2073 are designed for high-performance RF applications requiring ultra-low noise figures as low as 0.34 dB, together with high gain and linearity.
