2.5 - 4 GHz S-Band Receive VGA Module: QPM2101 Datasheet

Source: Qorvo

The QPM2101 is a GaAs multi chip module (MCM) designed for S-Band radar applications within the 2.5-4.0 GHz range. The device consists of a T/R switch, a transmit path which is a low loss pass through, and a receive path consisting of a low-noise amplifier, a digital attenuator and a driver amplifier. The receive path offers 30 dB of small signal gain and 1.0 dB noise figure. It includes a 6 bit digital step attenuator (DSA) with 31.5 dB gain control range. It can deliver 13.8 dBm of power at P1dB with 32 dBm of output TOI. All functional MMIC blocks can be enabled or DC powered off with internal control circuitry. All control signals use CMOS compatible logic. The response time of signal control is 43 nS typical.

The QPM2101 chips are fabricated on Qorvo's GaAs 0.25um process. The 7 x 7 OVM QFN surface mount package, coupled with a proprietary die-attach process, allows the QPM2101 to perform well at extreme temperature ambient. Its compact size supports tight lattice spacing requirements needed for S - Band phased array radar applications.
