Multi-Channel Wireless Transmitter from LPRS now offers
Remote Control of Frequency Channels
Richardson RFPD, Inc. announced immediate
availability and full design support
capabilities for a new 200 W solid state,
broadband, high power pallet amplifier
featuring Freescale Semiconductor, Inc.
(Freescale) enhanced rugged LDMOS
devices.
The RPAP470860M200 is a highly linear
pallet amplifier designed for use in the
UHF band. Utilizing Freescale‘s newest
50 V rugged RF LDMOS, the pallet is
ideally-suited for systems broadcasting
LPRS announces the availability of the latest
version of the CDP-TX-05MP-R compact
size multi-channel transmitter module from
Circuit Design. The new version features
additional control pins for remote frequency
channel control offering designers a more
versatile solution. Applications for CDP
wireless modules available from LPRS
include; remote control devices, security
and alarm systems, telemetry, monitoring
and tracking systems CDP-TX-05M-R and
CDP-RX-05M-R are low power narrow
band FSK transmitter and receiver modules,
designed for industrial applications operating
at sub 1-GHz. The modules contain
most of the components necessary for radio
transmission in very compact packages. The
RF channel is fixed but selectable within 4
preprogrammed channels. The receiver is
double-superheterodyne and equipped with
a SAW filter, ensuring high sensitivity and
very good selectivity for stable and long
range communication. The frequency table
can be customized to meet the customer‘s
requirements.
The new CDP-TX-05MP-R transmitter
has additional connection pins JP1 and JP2
allowing frequency setting to be performed
remotely. Both 434 MHz and 869 MHz band
versions of the existing CDP-TX-05M-R are
now available, however the new programmable
CDP-TX-05MP-R is only available
in the 434 MHz band version. The CDP-
TX-05MP-R will work with the 434 MHz
band version of the CDP-RX-05M-R.
Key features of the new CDP-TX-05MP-R
transmitter family include; 4 pre-programmed
RF channels at 434 MHz, RF output
of 10 mW at 434 MHz or 5 mW at 869
MHz, PLL controlled VCO, data rate 100
to 4800 bps FSK, double superhetrodyne
receiver, sensitivity -120 dBm (434 MHz)
Richardson RFPD Introduces New 200 W, DVB-T Pallet
Amplifier
under the digital television standards.
The RPAP470860M200 offers high gain,
efficiency and power in a small pallet
footprint, using advanced broadband RF
matching networks and RF LDMOS transistors.
Matched for 50 ohms input and
output, the pallet can be easily combined
to provide higher power when required.
Key features of the
RPAP470860M200 include:
- 470-860 MHz frequency range
- 19 dB gain
- 200 W of linear power (DVB-T)
- 50 ohms input/output
- Featuring MRFE6VP8600H
- Over-temperature protection
- 26% Efficiency under DVB-T signal

and -116 dBm (869 MHz), R&TTE (EN 300
220) approved and RoHS compliant, wide
operating temperature from -20 to +65 ºC,
power requirements of 2.2 V 21 mA (TX)
3 V 28 mA (RX) and very compact sized
transmitter 22 x 12 x 6 mm.
In addition to designing and manufacturing
the highly successful easyRadio Advanced
(eRA) wireless modules in the UK,
the full LPRS product range now includes,
Raspberry Pi and Arduino Shield wireless
platforms, the IQRF range of wireless networking
components, the IQVC range of
visual control panels together with antenna,
wireless key fobs and a wide range of sensor
products.

Solutions Announces New
Broadband Diplexer for
CATV Applications
M/A-COM Technology Solutions Inc.
announced a new Broadband Diplexer,
specifically designed for CATV
Customer Premises Equipment (CPE)
applications. The MAFL-011013 is a
high performance 42 /54 MHz Diplex
filter ideal for real estate constrained
CPE applications. The MAFL-011013
delivers excellent temperature stability
and repeatability in a small 27 x 13 mm
package, allowing the customer quicker
design turns. Unlike competing
discrete and CAN solutions, the filter
is a 75 ohm surface mount diplex filter
device that boasts excellent insertion
loss and isolation.
The MAFL-011013 is ideal for customers
looking for a diplex filter with
repeatable high performance in a small
outline package, said Graham Board,
Product Manager. This 42 / 54 MHz
split targets North American cable and
is a cost effective filtering solution for
constrained CPE applications.
