Hittite Launches New IF/Baseband Processing Product Line!
- New Baseband Products Ideal for Zero IF Architectures
MA, 03/22/2011 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
communication & military markets has introduced the IF / Baseband Processing integrated circuit product line which
includes two new baseband compatible products that combine excellent performance with flexibility and low cost.
HMC960LP4E dual digital
variable gain amplifier and the
programmable low pass filter with driver, meet the demand for a universal multi-standard, wideband/carrier,
transceiver, which is compact and capable of processing complex high density constellation signals.
HMC960LP4E is a dual
channel, digitally programmable, differential variable gain amplifier. It supports discrete gain levels from 0 to
40 dB, in 0.5 dB steps which are smooth and precise. The dual differential
HMC900LP5E filter features
0 or 10 dB input gain settings and supports arbitrary bandwidths from 3.5 MHz to 50 MHz. Once calibrated, the
accuracy is ±2.5% of the desired bandwidth. The 6th order Butterworth transfer function delivers superior stop
band rejection while maintaining both a flat passband and minimal group delay variation.
HMC960LP4E can be combined with the HMC900LP5E to provide a complete direct down conversion baseband line-up that
drives a pair of Hittite I/Q channel Analog-to-Digital Converters (ADCs). In such a design Hittite’s new
HMCAD1520 12-bit ADC with
its dual channel, 320 MSPS sampling rate would provide the common mode control voltage to the variable gain
HMC960LP4E, a feature
that greatly simplifies the ADC interface.
The HMC960LP4E and the HMC900LP5E offer high linearity, very
low noise, excellent quadrature balance, high precision and superior RF isolation between channels. These features
enable the receiver designer to overcome the challenge of rejecting out-of-channel interferers while maintaining a
perfect noise versus linearity trade-off.
The HMC960LP4 is housed in 4 x 4 mm plastic leadless surface mount package and the HMC900LP5E is housed in a 5 x 5
mm plastic leadless surface mount package. Both products provide excellent temperature stability from -40 °C to
+85 °C. Released data sheets may be found at www.hittite.com.
Samples and evaluation PC boards are available from stock and can be ordered via the company’s e-commerce site or
via direct purchase order.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
