Wideband amp modules

Hittite has released two MMIC-based connectorised power amplifier modules for broadband instrumentation, test equipment and communications applications from 10 MHz to 15 GHz.

The HMC-C037 is a GaAs PHEMT MMIC, 0.5 W wideband power amplifier and features an integrated heat sink and EMI filtered DC terminals. The device typically delivers flat 12 dB gain up to 12 GHz, making it suitable for broadband instrumentation, laboratory and test equipment applications, as the need for band switching is eliminated.

It also provides up to +37 dBm output IP3 and up to +28 dBm of output at 1 dB compression. Gain flatness is at ±0.3 dB from 2 to 15 GHz, while the saturated output power is 0.5 W up to 15 GHz.

The HMC-C037 and the HMC-C036 have identical electrical specifications. The primary difference between the two devices is that the CO37 is offered with an integrated heat sink, while the C036 is offered in a miniature, hermetic module.

The I/Os of both are internally matched to 50W and are DC blocked. Both amplifiers feature integrated voltage regulators allowing flexible biasing of both the negative and positive supply pins, while the internal bias sequencing circuitry ensures robust operation.
