The QPM2100 from Qorvo is a GaAs Multi-Chip Tx/Rx Module (MCM) that operates from 2.5 to 4 GHz. The MCM is fabricated on Qorvo's GaAs 0.25um process and is coupled with a proprietary die-attach process that allows it to perform well at extreme temperature ambient. It consists of a Tx/Rx switch, a transmit path that is a low loss pass through, and a receive path that consists of a low-noise amplifier, a digital attenuator, and a driver amplifier. In the Tx part, the module has an insertion loss of 1.2 dB. While on the RX side, it delivers a small signal gain of 30 dB with a noise figure of 1.2 dB and P1dB of 14.5 dBm. It also has a 6-bit digital step attenuator (DSA) with 31.5 dB gain control range. All functional MMIC blocks can be enabled or disabled with internal control circuitry. All control signals use CMOS compatible logic, whereas, the response time of signal control is less than 15 nS.
The QPM2100 is available in a QFN surface-mount package that measures 7 x 7 x 0.8 mm and supports tight lattice spacing requirements needed for S-band and phased array radar applications. It is also suitable for use in Electronic Warfare (EW), and commercial/military radar applications.
