Hittite Launches New Programmable Bandwidth Low Pass Filter
-- New Filter Supports 72 MHz Channel Spacing in the
Chelmsford, MA, 04/16/2013 – Hittite Microwave Corporation, the world
class supplier of complete MMIC based solutions for communication & military markets has
a new addition to its IF/Baseband Processing integrated circuit product line.
A 6th order, programmable bandwidth, fully calibrated dual Low Pass Filter (LPF), the
features programmable 0 or 10 dB gain and supports arbitrary user programmable, bandwidths from
5 MHz to 72 MHz. When calibrated, the programmed bandwidth is accurate to within ±2.5%. A built-in
filter bypass option enables wider bandwidth while maintaining programmed gain and common mode
features an integrated ADC driver, programmable input impedance, and adjustable output common
mode voltage from 0.9V to 3V with a 2 Vpp signal. The output common mode can be also be adjusted
lower than 0.9V common mode to effect a seamless interface while achieving maximum performance.
Programmable bias settings enable performance/power dissipation trade-offs optimized for each
application. The 6th order Butterworth transfer function delivers superior stop band rejection
while maintaining both a flat passband and minimal group delay variation.
is footprint and register compatible with the previously released HMC900LP5E programmable bandwidth
LPF and supports wider signal bandwidths demanded by the new 72 MHz channel spacing standard
set by the microwave radio market.
Hittite’s IF/Baseband Processing product line
is now comprised of two programmable bandwidth Low Pass Filters, the
and the HMC900LP5E, and the HMC960LP4E dual digital variable gain amplifier. These devices enable
the design of a universal hardware platform that is field programmable and supports numerous
RF frequencies, standards, and signal bandwidths. Together with Hittite’s Wideband PLLs with
Integrated VCOs and Analog-to- Digital Converters (ADCs), the IF/Baseband product line enables
Hittite’s customers to address all regions, standards and bands of operation with one hardware
platform; thereby streamlining their supply chain and eliminating the need to support frequency/standard/bandwidth
Both products are housed in a 5 x 5 mm plastic leadless
surface mount package and 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.
